After the nearby Party City closed down, I quickly turned to Yelp to find an an alternative location to purchase balloons for my daughter's birthday. I was able to buy a "bouquet" of about 10 latex balloons and, plus a large unicorn balloon, and a large number nine balloon, with the total coming out to about $50 (helium is expensive!!). The lady who helped me at the counter, was super patient and helpful, even advising me to upgrade to the longer lasting helium since I wouldn't need the balloons till the next day. The balloons did, as she promised, last for a good couple days, and helped make the party feel festive. Great customer service and I'll be back for other party needs! read more

Diddams in Mountain View is the best place to order Ballons for delivery and pickup. Thanks to Ruben I got the best services for creating the best balloon bouquets and fast same day delivery. I also spoke to the store manager who was very nice and mentioned. Hit an excellent service from Ruben on the phone. Thank you! read more

In a valentines day they were the best option because most of the other stores ran out of helium and they charge so much for a balloon. Diddams prices were decent and they helped me immediately with my order although they we're busy the were able to get me out there within 10 min. Loved the service. And they have a verity of balloons. read more

Diddams Party and Toy - Party Supplies Near Me - Mountain View, California

I love that we have such a wonderful party store nearby!!!! On May 21st, 25 I just happen to get negative vibes from the brunette woman working in the balloon area. She was cold, didnt greet me even after I said hello, did not offer to help me nor did she say thank you for waiting i'll be with you as soon as I'm done. In fact, she seemed annoyed. The guy, Eddie, noticed and offered to help me. He was VERY kind, friendly and quick to help. read more

The man at the front/cashier is super unpleasant. Always acting like he is doing me a favor when I go to pay for items I bought. I hope his colleagues can observe him and let him know the right way to provide service to paying customers. I would have given this unpleasant fellow a pass cos everyone can have a bad day, but three times in a row over a month's period, I have to call it as I see it, a super unpleasant person. Everyone else in the store is helpful and nice and they have a great selection of things. I'll recommend shopping there if you are having a party as it is truly a great party store read more

DO NOT use them for balloon delivery. I wanted several hundred dollars of balloons for a nonprofit banquet. I texted back and forth for several days with the number provided online just to confirm they could deliver and in the end she just stopped responding and I had to scramble last minute to buy balloons elsewhere. Not reliable. read more

Only diddams store close to me. I came here to buy to party supplies for my sons birthday. This place feels a lot more fun and exciting to be buying for an upcoming party compared to other party store. Everything I needed to buy was in stock and more. read more

Had to order balloons. Amazing staff: friendly, knowledgeable, and patient with all my questions. I was served so quickly and everyone was a pleasure to talk with. Thank you! read more

It's been years since I've been in the store just because I don't live in Mountain View anymore. But before I moved they had already taken over the store that was next to it and expanded their Halloween section. So coming here I already knew how big it was but the full size of it just kind of shocked me again lol. We were greeted as soon as we walked in, they have a huge selection of balloons to the left and they will even blow them up for you. As soon as you walk in and you look slightly to the left I think that's where they have like the seasonal items because they had a huge Valentine's Day display there, behind it they have a huge and I mean absolutely humongous candy selection which is amazing because they have a lot of like nostalgic candy that I haven't seen in years. They tend to organize the store based off of whatever event you're looking for so pretty much anything you need is going to be in one spot. We needed some retro items for our daughter for spirit week this week so since we were going to be in Mountain View we decided to come here and we found a cute poodle skirt and pink glasses, and white poodle socks. I'm not sure who had more fun in here, me or my kids to be honest. They apparently also sell bath bombs here! This kind of shocked me but it was really cute because they were shaped like donuts and they had like rainbow sprinkles on top. I also needed to make some Valentine's Day treat bags so I was able to find some pencils and little pads of paper and erasers here which was perfect! I really enjoyed coming here because they had exactly, and I mean exactly what I was looking for, and I don't feel like I spent too much based on what I was getting. And also it was kind of hard to find retro clothing for my kid anywhere else so just the fact that they even had it in stock and right there for me to just take home, I would've paid anything for it haha Overall this location has ample parking, a huge Halloween section, plenty of party decorations, friendly staff and fun nostalgic candy to bring the kid out of you. I would absolutely recommend coming here for party stuff, event planning, Halloween, even fun dress-up days for your kids school! read more

Diddams Party and Toy - Party Supplies Near Me - Mountain View, California

I can't say enough positive things about this store, truly, they helped pull off a miracle! With impossibly short notice, Diddams Party and Toy was able to make a kid's dream come true by delivering numerous mylar balloons to the hospital. Angelica, the woman we worked with from the store, was incredibly patient, kind, and professional. She went above and beyond in helping to coordinate the order and ensure it was delivered in an incredibly timely fashion, that exact same day. I had never heard of this store before, but now it will be my go to store for party supplies, whatever that may be! I had originally placed an order with Party City (not knowing about this store) and they cancelled my order without any communication, even when it was supposed to be delivered the same day. Diddam's showed how professional and reliable they are and how they go above and beyond in making sure needs are met. Thank you, Diddam's, for helping make a child's wish come true :). read more

This store had hands down the best selection of party supplies! They had many many aisles of tableware as well as coordinating decor. Whether you need child birthday supplies or wedding supplies, this is the place! This location will be the closest to South Bay by 2020 as the Almaden location has lost their lease. read more

Diddams is an awesome sprawling place. We head to the kids toys section where they had a lot of educational toys and some weird stuff. My kinda mix. Usually we just wander the aisles. It wouldn't be a bad place to get obliterated in an earthquake. Plenty of parking and right near the little gym. read more

Yoooooo this place and especially the staff are amazing! I was in a huge hurry tonight and when I came in...it's quite a large spot so was a bit lost at first...they noticed and pointed me right toward the costume section at a side part of the store. There another helpful and attentive team member (in a cool costume btw!) was in the section and asked exactly what I needed and how she could help. It was so perfect I literally was in & out with a quickness and soooooo very satisfied with my Harry Potter costume; and all because the staff was just top-notch (plus a great selection of costumes too). GO HERE OVER SPIRIT!!! read more

Love it here! amazing family owned business!! Please support! Here for all your halloween needs

There's a wide range of positive qualities of Diddams and the products they provide but I cannot get over the TERRIBLE customer service of their banner/t-shirt department by their new point of contact Julissa. I've worked with Tomer in the past and had absolutely no problems with their services and communication. He always did an amazing job with both design layout and ensured a smooth, error-free experience. Tomer's replacement, Julissa, is the complete opposite and downright dreadful to work with. Where in the stockroom did they find her? OMG! She's rude, irresponsible, incompetent, and a poor addition to the once amazing banner team. I'm an event planner by trade and have had a couple projects previously made by Tomer without a hitch. My recent banner order, however, was botched twice by this gal and then she had the audacity to say that I'm responsible to pay for both the botched and new banner order. When asked to speak with the store manager, she claimed that she was the Manager. You can have a temperament of a saint but I guarantee you, this gal will take you to hell and back with her argumentative demeanor. To make matters worst, she treated known acquaintances of mine the very same way. I suspect she treats customers this way because she's the only POC in that department but if Diddams truly cares about their customers and the growth of their business, they should seriously re-evaluate having Julissa run the banner department. read more

Generally Diddams has what I need in the colors I want. Sucks that every sale is final.

I wish I can give this store a below zero star but there is no such thing. So I am writing this review in hope they do something about that employee. I was standing outside the store when the employee chased me down kept asking me for the receipt. The stuff I was holding was all from world market I just bought from there. I am wondering is it because I am Asian that he thinks it's okay to accuse me of stealing from your store I will never go there again. racist employees. read more

Young female cashiers here are rude and unwelcoming. I usually come here regularly for birthday gifts and balloons. Their mylar balloons are incredibly fragile and easily pop and tear -- a recent thing. I will not shop here anymore. read more

Before the pandemic this used to be one of my favorite places to shop. Now it's a complete mess. Recently I went there to get some small plates for my wife. She wanted disposable and clear. I finally found them after asking many people. On the shelf, it showed a set of 5 as $5.99. Went up at the register and they told me it was 9.99. I told them that was the price for the larger plates and they said no somebody moved them. I paid. My wife told me to return them. I went back to return them because they were too pricey, and, even though they had taken the money out of my account immediately., they said it would take five business days to return it. I smiled nicely at the lady and said geese. And she got all grumpy with me telling me that it's the holidays and it's really busy times. read more

They do have a lot of things there, that are mostly party-related. Plus a surprising quantity of jelly beans, M&Ms, candles... But the place is so confusingly organized, I've never been able to go without asking where the item I'm looking for is stocked, and I'm too intimidated to walk the store and get the layout down. It's definitely not a bargain, either. Still, there's no better place for go-to party essentials. My favorite encounter from a surprising number of visits in the last month: Me: Excuse me, do you have any colored contacts? Cashier: No, but those are way cool, aren't they?! I don't even know where you'd *buy* those! I do. Perhaps at a party headquarters. It's the headquarters, for goodness sake! It should know what all the party troops are doing! It should know where to find colored contacts! Nothing says 'party' like wolf-eyes! read more

For people who want to collect Sonny Angels, this store does not have any. When I asked the worker, he said he didn't even know what they were. The store had an ok selection of things though, and was pretty clean which was great. Overall an enjoyable place to shop around / look around in, albeit no Sonny Angels. (a previous reviewer said they had a huge collection) read more

They did away with their teacher discount and replaced it with a 5 star program. Their wifi was down so I couldn't check that. The young sales girl was rude, and her co worker was so chatting up another employee, that the cashier could answer my questions . Guess I'll have to look for a new place. I'd give 0 stats if possible. Side note I usually shop here 5x a month. Not any more read more

TL;DR: Purchased 2 pairs of mylar balloons. First pair both deflated after couple hours Clerk replaced them. Second pair, 1 burst and 1 deflated. Tried explaining to clerk it could be defective batch of mylar balloons, clerk rudely blamed me for mishandling. My family and I have shopped at Diddams for balloons for years. We are usually very happy with our purchase with no issues. This time however, I went back to exchange the 2 mylar balloons because they had deflated a couple hours after purchasing. The person replaced the 2 mylar balloons. I took them out to my car, put it in my empty trunk for no longer than 1 minute, one popped and the other deflated. It was hot that day, but not hot enough to burst a mylar in a minute. Having had the second pair of mylar balloons go bad, I went back in to tell the person something is wrong with that batch of mylar balloons. The person rudely assumed that it was my fault that they were defective. I calmly explained what happened, but they didn't seem to like my answer and insisted it was my negligence. Reluctantly, the person replaced my balloons and waived a $1 difference. I appreciate that the person replaced the balloons and waived the difference, however, i don't appreciate the person blaming me for an issue that one specific mylar balloon had 4 times in a row. You would think that it could be something other than user error at that point. I now feel extremely uncomfortable purchasing balloons from there knowing I could be blamed and humiliated again. read more

Mountain View location had party supplies for St. Patrick's!! Yes please....Green balloons, party "poppers" and necklaces too. Very festive display. The balloons lasted a long time (with/without helium) and the "poppers" were quite nice with plenty of streamers. Good party fun for us I'll be back for Easter. read more

This place is very underwhelming from the outside, but appearances are deceiving. Once inside, it's like a wonderland of happiness!! I mean, party supplies and all kinds of toys and even candy and treats. I can literally spend hours going down every aisle and the day would be gone. So, I come here only with a list and specific items I am looking for. But it is a happy place to come, outside of the major holidays. It gets kinda crazy around October and New Years. Be warned. I am impressed with the staff and their knowledge of inventory. read more

This is the best party store in the bay!!! I love the wigs balloons costumes and more! One stop shop for all your party needs! Great people full of love and diversity and great products full of fun! :) read more

PARTY!!! Strolled through here before the Halloween shopping chaos begins, but I would imagine this place is fun all year long. Every kind of toy, puzzle, stuffed animal, balloons, wig, party decoration etc read more

10/30/21 went to buy JJ's Harry Potter costume and was surprised that they offered to try the outfit before we bought it. The salespeople were very friendly, checkout was easy as well as parking. We often check this store out before we go to other stores and I am happy we found the gown for JJ. read more

Love coming here, especially for the balloon selection and the sticker wall. The sticker wall is so unique, I hope they continue to restock it because last time I went, the wall was almost bare. This place beats most other party stores by far! read more

Every time we having a kids birthday party we come here for one thing or another that we can't find at party city or the dollar store. Stuff here is a little more expensive then those other places. This place gots everything party related and also got A pretty good selection of games. Ive never venture into the costume section yet, but I know there is one in the back comer. If you don't mind playing a little more then other places this your place But I do suggest you compare prices first before you buy or save the receipt so you can return if you find it cheaper else where. read more

Customers beware. The store does not inform customers of their return policy at check out, especially regarding items they deem to be "Final Sale". I purchased several packages of tights and there are no written signs stating that they are final sale nor was I told at check out. The receipt states that returns are accepted within 30 days with some exceptions*. The exceptions are not detailed anywhere on the receipt and was not verbally communicated upon check out which is a common practice for retail businesses. I was not provided a one time courtesy for a return, exchange, or store credit when it was the fault of the store for failing to inform customers of the return policy. My sister purchased costumes and asked if they could be returned. She was told by a store associate that she had 1 week to return. We came in 5 days later to return and was told that we only had 24 hours to return. I wanted to purchase a masquerade ball mask and there were 2 left but not in good condition. The one I chose had a broken feather. A store associate who helped me out said I could get 10% off. The store manager looked at the mask and said there was nothing wrong with it. Then I showed her the broken feather and she said she would only give a 5% discount. I'd give this place 1 star for their customer service and failure to clearly inform their customers of the return policy. Even worse, store associates provide inconsistent information. I only bumped up the rating to 2 stars in this review because of their wide selection of party accessories. *While writing this review, I came across an image posted on Yelp in October 2015 with the store's return policy and its list of exceptions. The sign is not displayed in a large format and in clear view for all customers to see. I believe this was done purposefully as the bottom line is clearly more importantly than customer service. Also, I don't see tights on their list of exceptions (unless they view tights as a seasonal item). read more

Not spending any of my money here since they have a completely racist section aimed at Native Americans down to an arrow in the head. When I walked out of the store with clearly nothing in my hands I was followed and asked if I had paid for my stuff so thanks for that awful experience too. Absolutely horrible. read more

Expensive merchandise and rude staff. I asked them to split my balloons in 2 groups and they gave me a nonsense reason for not doing that. The guy told me he doesn't have time to argue with me and he will just do it the way he wants. We used to prefer to go there instead of a chain like party city but party city has better prices and customer service. read more

Like any halfway decent secret magical world, the land of Diddams lies hidden behind a blah entrance that nobody would notice--nor begin to guess at the acres of fairy dust waiting inside. If you're anything like me, you may need to ask a grownup to hold your wallet, lest you buy allllll the lollies, confetti and stickers on Technicolor display. They call it a "party store," but that's an understatement-- this sprawling wonderland has nothing you actually need--but literally everything you could ever want to be happy. Think aisles of glitter. Tiaras galore. Pinwheels a plenty. Grass skirts and cone hats and six trillion kinds of candy. At this writing they had four aisles of Halloween costumes. (From adorable and tiny--to Vegas-level sass.) Most of it was cheap, but not toooo cheap if you kwim. I think I may have bought some gold fingerless gloves, a pair of black angel wings with real feathers, an obscenely long stuffed boa constrictor with two-tone sequins...and a truckload of blowpops. Why? Because I'm 12. And yes, yes I do I have a sugar and glitter hangover. But don't you judge me, lady. You'd have done the same. read more

If you're looking for balloons, themed party ware and party favors to throw your kid an awesome birthday party, then look no further than Diddams. If you're looking for a huge selection of Halloween costumes, accessories or even funny masks (horse head, anyone?), then look no further than Diddams. Or if you're just stopping by for art supplies, wedding decorations, Christmas-themed table ware, jigsaw puzzles, board games or toys... yeah you'll find all that here too. I stopped by a couple days before Halloween to pick up a bandana to complete my cowboy costume. I was pleasantly surprised to see several aisles packed with costumes of all types. These are the cheap pre-packaged variety, but who are we kidding, how many times would a person wear that Naughty Lady Cop outfit? (Well, I suppose it has uses apart from Halloween...) Prices throughout the store were pretty reasonable. I was blown away by the size of the store and the enormous selection of stuff crammed into every available space. Every little corner you scrutinize, there's something new to find. And so I found a pretty nice looking bandana, next to all the cowboy stuff, for only $2. Yeehaw! read more

This store is extremely overpriced (for what you get), and employees are quite unfriendly. It does has however everything you could possibly need for a party if you are short on time and don't mind the premium. My biggest pet peeve is their low quality balloons. Every time I've come here, their balloons have deflated within 4-5 hours. I don't expect latex balloons to last 24 hours, but if I purchase balloons in the afternoon, I expect them to last for an evening party. Not so with their balloons - even their mylar balloons deflate within a few hours, which should technically hold air for at least a week! Adding insult to injury, they require you to purchase one of their balloon weights. So the bottom line is that you are going to pay top dollar for a low quality balloon product. read more

I've been to Diddams Mountain View plenty of times now. I'm giving them a 5 star for my recent order from them. We had a grand opening at my company and was in charged of order some decorations. Lisa, balloon specialist, was very responsive and was able to take my order within 5 days before the event. I ordered a full balloon arch that had "grand opening" in silver letters on the front and two balloon columns with a star on top. It was fast and easy to order. We spoke via phone and text messaging. Balloons were delivered to me on the day of the event. They give you a two hour window. The man who dropped it off was very kind and professional. Without the balloons, I feel like the grand opening wouldn't have been so successful! They were beautiful! I also order a banner from them. They were able to take my order the day before the event. Kerria helped me. Again, service was very fast and simple. We talked via phone and email. They were able to deliver the banner along with the balloons which made my day of the event so much easier Thank you again Lisa and Kerria for your fast and friendly service! Will definitely come back and order from you guys again. As for the store, they have plenty of party supplies and toys. read more

Absolutely appalled. Was shopping for a birthday party and overheard the cashiers grossly accusing a customer who had just left the store of trying to steal things. This is not the way to run a business. Immediately returned the items I had picked up from the shelf to purchase. Will not be coming back to this business. read more
