    We like Crumbl because they have new flavors every week. We are not Benson Boone fans, but surprised that they have Benson Boone's Moonbeam Icecream cookie for the week of 6/23-6/28/202,5, and it looked quite attractive. We ordered that one, chocolate cheese cake, and wedding cake cookies. Benson Boone's Moonbeam Ice Cream cookie- it had cookies & cream pieces with moonbeam ice cream-inspired lemon, berry, and marshmallow toppings, and finished with a sweet white drizzle and a final sprinkle of cookies & cream. We liked this moonbeam flavor. Chocolate Cheesecake Cookie - it had cookies & cream crust, and it was dressed with chocolate whipped cream, a pool of chocolate ganache, and chocolate curls. It was a bit too sweet for me. Wedding cake cookie- it was a soft, vanilla bean cookie topped with vanilla and raspberry frostings and white chocolate pearls. It tasted so good, and we liked the white chocolate pearls so much. The color looked so attractive. FYI, for the week of 6/23-6/28, it had a special Crumbl x Benson Boone box, and the staff also gave out his stickers. You will like it if you are his fan.

    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.

    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.

    Delicious!!

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

    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!

    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!

You shoud bring cash or they have a $0.50 fee on credit card paymenys under $15. A bit pricey for how tiny the snack is. To my surprised they were individually packaged and this location had multiple flavors compared to the locations I've been to prior. They were individually wrapped and premade, not as fresh as what I have had prior. We got 2 of the walnuts, 2 redbean filling, 2 chocolate looking ones, and the rest in original custard. The others were fun to try but the custard is my favorite. A nice snack if I'm already at this H-Mart picking up groceries but I wouldn't go out of my way for it. I like the locations that sell them fresh, when they're warm and tasty. The taiyakis are made fresh to order but it's a bigger pastry.

The Signature Mixed Noodle has a scallion and soy sauce taste, and it comes with plenty of thick and chewy round noodles.

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 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.

However, after the hour, I reconnected and it refreshed the timer. For my coffee, I decided to get an iced Dalgona latte. They provided many pieces of Dalgona. I did ask to get this at regular sweetness and ice. Overall, after the Dalgona dissolved with the ice, it felt like a good amount of sweetness. It was decent, but I've come back to try other drinks!

    Apparently all locations of the Mugs have been bought out and rebranded. The location in DB is now…read morerebranded as Outpost Coffee. It appears that they are still in their transition phase as there are still signs of "the Mugs" throughout, including the same menu and company info poster. I got the Banana Caramel latte and it is so good! Slight sweet banana flavor but doesn't overpower the espresso so it still tastes like a coffee drink. Plenty of seating for working and just hanging out. Parking is plentiful, staff is nice, just wish the noise of the refrigerator case wasn't so loud so I could enjoy the background music.
