Ronny was absolutely amazing! I brought my high school students with autism on a field trip, and she made the experience so special for every one of them. She took the time to help each student order, was incredibly patient while they counted and paid for their ice cream, and made them feel comfortable and included. Her kindness and understanding made the entire experience a success. Thank you, Ronny, for helping make this such a memorable field trip for my students. We truly appreciate you! read more

If you want expensive ice cream ,go here 20 dollars for a small coffee and a medium size of plain vanilla with a few pieces of oreos was 20.15 $ what in the actual hell Never coming back ,I rather go to the market and grab a tub of ice cream for a few dollars read more

Went there for takeout and there were 2 girls helping at the counter, both were really nice and one was in training. I got the cup and cookies chaos and my husband got a custom made with bananas ice cream. It was very tasty but too expensive. 2 ice cream was $25. Way too much. They charge $1-$2 more than Brea cold stone :( read more

Well for some reason I don't like their custard flavor . Service is great and the store is always clean . Parking is kind of tight due the crunch gym being so close. read more

Cold Stone Creamery - Ice Cream & Frozen Yogurt Near Me - Diamond Bar, California

I have not been to a Cold Stone in a very long time. I like the concept of them making the mixture of ice cream and topping in-front of me, but think the prices are a little out there. The flavor of my ice cream had a weird aftertaste to it, not sure if it was from the stone they mix it from or the actual ice cream. Our server was kind and friendly. Inside was open and clean. I was surprised of how empty it was inside read more

Just in time for Summer and the heatwave! Diamond Bar has a new place in town! So glad to see my favorites on the menu, like the "Apple Pie Ala Cold," and Banana Caramel Crunch, plus many varieties if you are a chocolate lover! I saw a new Barbie-inspired ceeation "All that Glitters is Pink," which is cotton candy ice cream with sprinkles on top! I always get individual servings, but they do have family packs from $16 to $99. Try one of their "ready to go" ice cream cakes to treat the family. They look ALMOST too good to eat! Available in strawberry, chocolate, cookie dough and more. With modern technology, you can place your order online, and it will be ready when you arrive. I am beyond excited! Drop on by, and don't forget to tell 'em Rosemary sent ya! read more

The lady doesnt know how to mix the ice cream!!! I wonder if she got trained... come on it is cold stone!

Great service!! Convenient parking and handicap accessible clean fresh atmosphere!! Sensitive to concern for nut allergies.

I've been to many Cold Stone Creameries in the past, and I've always had a positive and consistent experience. I mean, it's literally just mixing ice cream and toppings, how hard can it be? Apparently pretty difficult at this particular location. My 2 orders both were mixed with practically zero effort. The cookie dough chunk was still completely intact, and all the toppings were just folded into the inside of the ice cream. We didn't discover this until we got home because our expectation is that it's usually fine. I would avoid this place and go to the Baskin Robbins down the street. At least they know what they're doing. read more

First time at this location. Arrived about 30 minutes before closing. My daughter and I ordered what we wanted. The guy working seemed to be in a rush, yet there was no one else in the store at the time. I didn't get to eat my ice until just yesterday. Come to find out he didn't use coffee ice cream like I requested at the beginning of my order. Walnuts weren't even chopped in they were left whole. The music inside the ice cream shop was a bit loud. It was just a lazy effort in making a simple ice cream order. I will stick to the two other locations I go to and get exactly what I ask for. For the prices we are paying we should be receiving our order exact especially when it's just two people in the store. read more

Had to throw my ice cream away about four bites in. I didn't want to, but it was clearly not "freshly made" as the advertisement on the door suggests. I got the vanilla lite ice cream as my base, and it was so gummy and icy, that it was not edible. You know the top layer that develops on ice cream that hasn't been used in awhile? That is what I had, clearly. Also, my husband had an allergy that we needed to validate was safe, and they said they "didn't know". I asked if they had a allergy guide and they were able to ask someone in the back but it took some coaxing. I get it, they're kids, but please train your employees to have an allergy guide available if people ask. Oh, and maybe don't serve old ice cream. Thanks. read more

Beautiful new location! Cold Stone has excellent ice cream and other dessert options, such as ice cream cakes, ice cream cupcakes, ice cream sandwiches, & etc. ! High quality ingredients that won't disappoint! The drawback is that the cost is high (you get what you pay for , right?)? About $38 something total for 3 kids and 1 adult ("Like It" single scoops which included cones) This place is extremely clean and service is excellent!! The ice cream is sooooo good !! read more

Cold Stone Creamery - Surrender to Strawberry and Chocolate Devotion with vanilla ice cream - Ice Cream & Frozen Yogurt Near Me - Diamond Bar, California

This Coldstone's does not cater to patrons with allergies. At many other Coldstone's, they typically have a small "Coldstone slab" to mix ice cream to prevent cross contamination. I commend the young employee who offered to mix the ice cream in the back, I'm guessing on some plastic wrap? With that said, I will say the staff needs to be trained on making the flavors. In both of our orders, one made in the back and the other made in front of us, the amount of mixings was lacking and the level of effort of "mixing" ingredients was basically none. I went home with the banana intact and caramel just squeezed on top. My other order was cookie dough however there hardly any cookie dough. Luckily we used a coupon, but we didn't go to coldstones to get a scoop of plain ice cream. read more

came in about thirty minutes before closing. the person working was in a rush for no reason because it was just me and my mom. he was really lazy with prepping the ice cream most of of the mix ins were left in whole. not really a good look to be rushing people out of the store instead of getting it right the first time with the prices we pay. read more

Such an amazing experience. Fresh made Ice cream with great customer service. Will keep visiting only this location. Their oreo ice cream is no match with any other cold stone read more

Great workers that work at this cold stone, the service is excellent and the ice cream is delicious

Ice cream is good just like any other Coldstone I have been to. The store is small but neat. However, the worker who served me was not very kind and completely ignored me. She asked the people behind me what they wanted while I was standing in front of her waiting. In addition, she was rude and blunt with her responses. It felt like she was in a rush when there was only one other person in line. This location could thrive but needs to hire better employees. read more
