    Came in for 6 mini cookies and they tasted like chemicals. I called the store and was told to bring the cookies back. They gave us a new box, but those tasted like chemicals too. The girl working there said they don't use cleaning agents and don't spray, but we literally watched her holding a spray bottle and a rag. After trying the second batch and tasting chemicals again, I asked for a refund. Instead, I was handed a business card with a phone number for a different location. Then I was told I had to email for a refund. Absolutely ridiculous that for a defective product I have to jump through hoops instead of getting a simple refund right away.

    Delicious!!

    Delicious! Service was great! Had my order ready as I stepped in. Thank you This week cookies hit

    Our coworkers have brought over a variety of cookies and I have tried soooo many flavors already and the best thing is it's by Target! The cookies are really filling that I eating one is too sweet for me but they have a cookie cutter that cuts it into 4 pieces and we all have a sample of each one. My favorite is the classic chocolate chip cookie and I can't wait to try more new (to me) flavors in the future.

    Great Easter Haul!

    Great choice for Easter treats! The employees are all so nice, too. The inside is clean and the parking lot isn't full of traffic. Thsi is a nice location.

    Gimmicky! Not a good location, limited flavors and poor service. Been to several Crumbl locations, so I was excited to try this location when it just recently open up, sadly the experience was sub par. There was only 6 flavors, so we got one of each. All of them are powdery tasting, and very ordingary. The only one that was more representative of the Crumbl cookies I'm used to having is the peanut butter flavor. Plus, $5 for a cookie is definitely pretty steep for something that doesn't even taste good. Staff was not very nice, and didn't know how to smile. Very cold and rude. AVOID!

    Carrot Cake Cookie

    I must've gotten really lucky with the flavor I started with because I've heard that it can be a hit or miss. I've never been to Crumbl ever in my life and today was finally the day! The carrot cake flavor caught my eye so I was actually able to redeem that one with a coupon that I received. It was amazing. Of course, eating the entire thing at once is too decadent, but a few bites are all you need. The cream cheese frosting with the soft, chewy carrot cake cookie is perfection. I went super early in the morning so there was no line and the worker who helped me was really kind. I watched her assemble the cookie by frosting it and putting on the pecan garnish. This store is located right next to Starbucks so I feel like that would be a great combo.

    Needed to see what the hype is about and stop here last night for a sweet fix. Place was super cute and the decor had clean lines which I appreciate. The service is ok and I got The 4 pk cookie promo. To a slice off each one of the cookies and cream, buckey, the peanut butter chocolate and the chocolate chip. The peanut was probably the best out of the 4 but I didn't really care of the consistency, it just didn't taste like a cookie to me. It was more like a dense muffin? Got it off my bucket list. Won't be coming back for seconds at any of the locations.

    A new cookie spot has opened and it was my first time trying this place. They have other locations but I am glad they opened in the city of Diamond Bar. It is literally in the same plaza as Chilis, Starbucks, and Target. So if you are coming to this plaza you can go and try this new cookie spot. Got an order of six cookies two chocolate cookies and cream, two churros, one milk chocolate, and one classic pink sugar. Shared it between friends and my favorites are churros and the classic pink. I like these two the most because of the flavor it has. The classic pink tastes light and the churros do as well. There might be a tad bit too much frosting for me so I didn't have all of it. You can easily take it off if you are not a frosting person. But I would still say to try a little bit of frosting with the cookie. Overall I'm glad to try these delicious cookies they are unique and different.

    I have been to Crumbl before, just like this location. It is located in the same plaza as the Target in Diamond Bar. The store was really clean and nice. I like opening, so you could see the baking that they did in the back. It smells so good in there, smells like sweets and sugar! Like when you are baking cookies at home and the whole house smells. The team members were really nice. Everyone was very friendly, greeted me, and wish me a wonderful day! I went in to get a cookie. They all looked really good. There was a display of cookies at the register, so you know exactly what's there this week. They usually change your menu every week. So if you like something, make sure to go pack before the end of the week! Some cookies are sold cool, and some are so hot. Keep that in mind, when picking your cookie. I ended up picking the chocolate salted caramel. It was really nice. The chocolate cookie wasn't too sweet, so the caramel enhanced it. The sea salt really made it better. It was a little gooey, so messy to eat. But that's kind of expected! Cookies are about $5 - a little pricy, but they are pretty large. It's definitely a special treat to get!

    So happy to have a closer Crumbl! Appreciate the welcoming staff and fast service ordering on their tablet. Everything is standard inside the building and the box! The cookies are good as expected! I also like how they have a public table outside their door to sit down. Perfect place to chill, especially if you want Jimmy John's or Starbucks next door.

    Dropped by on a Wednesday night around 5:30pm. It was empty and no customers were inside…read more I decided to get the scallion oil noodles, a sausage, and a sweet soy milk. To be honest, the noodles were pretty salty for me, but my dad really enjoyed it. It was very flavorful and had lots of scallion oil flavor!

The Signature Mixed Noodle has a scallion and soy sauce taste, and it comes with plenty of thick and chewy round noodles. The Spicy Noodle Salad comes with a similar type of thick/round chewy noodles as the signature mixed noodle, but instead of soy sauce flavoring, it comes with a spicy (just slightly) chili and sesame oil sauce. This noodle also includes corn kernels and slices of iceberg lettuce as toppings. Again, plenty of noodles included in each serving as well. This is a very refreshing noodle to be eaten on a hot summer day! Great value considering the portion and taste. Parking wise, there are plenty of spaces as It is located within the Super Hmart plaza. Check it out when in the area. Also want to highlight the great service received as I came by the restaurant about 5-10min before closing. The staff was already in the process of closing, but when she saw me walked in, she was readily available to take my order and I was able to get my order after the closing hour. Definitely worth coming back to try their other dishes/wraps! Come and support our local small businesses.

    I came to charge my car and decided to give this tea spot a try because it looked incredibly busy…read more My thought was, it must be good, right? Luckily, I was right. I ordered the half sweet matcha with oat milk, and it was delicious. The portion size was generous, and despite how busy they were, my drink came out surprisingly fast. I loved that you can order from a touchscreen kiosk and easily customize your drink with all the available add ins. The menu is huge, but the digital ordering system makes it easy to browse and see all your options. The location itself is small with minimal seating, but it has a cute atmosphere and a great vibe. Overall, a solid spot for tea and matcha lovers, and I'd definitely come back to explore more of the menu.

    Convenient and Customizable -- A Solid Go-To My all-time…read morefavorite boba spot was Sunright Tea Studio, but unfortunately it's closed down, so I've been on the lookout for a replacement -- and this place has become my current go-to. What I love most here is the ordering experience. There are multiple large touchscreens where you can fully customize your drink -- sugar level, ice level, add-ons, substitutions, you name it. I almost always go for zero sugar, and the fact that I can do that easily is a huge plus for me. It's the kind of flexibility that modern boba shops should all offer. The portions are generous and the prices are reasonable, which is refreshing compared to some other spots in the area. Is it the most amazing boba I've ever had? Honestly, no -- but the ability to build your drink exactly the way you want it more than makes up for it. There's also a large display screen showing order status, so you always know when your drink is ready. It's a small touch, but it makes the whole experience feel smooth and stress-free. I'll be real though -- I probably drink more coffee from the Starbucks across the street than boba from here. At the end of the day, coffee feels like the healthier daily habit. But when I'm in the mood for something different, this place is where I'll be.

I went on a weekday before noon and had no issues with finding a spot. For ordering, they had a kiosk inside with pictures for reference as well. It does accept American Express. After ordering, it only took a few minutes before it was ready. As for the atmosphere, there were a few other people, but they were mindful of noise. The music was also moderate, so I was able to focus without any earphones. There was plenty of seating from the center table to seating at the wall and even window seats.
