“The food is very delicious, the restaurant is very beautiful, there is a lot of parking. Importantly all of the chefs are beautiful“

“Me encanto el lugar muy agradable el personal no se diga muy amables“

“Truly authentic Japanese restaurant! Food, service are excellent!! The quality is very much like in Japan. I have spent a lot of time in Japan over the years. Hard to find a better Japan restaurant than this, especially being far away from L.A., Torrance, and Costa Mesa. It's definitely my favorite place to eat sushi and anything else!“

“Warm welcome, kids friendly food tastes yum.“

“A certified Diamond Bar classic. Everything is solid here, from the pho, to the rice plates and appetizers. The pricing is reasonable (expect to spend in the low 10's per person) and portions are good sized. They have two TV's in the case you wanted to catch a basketball game or football game as you eat. Would recommend if you're in the area, but would not be a place you drive out for.“

“Read my post it's the best around“

“delicious food. good selection of meats. short wait for a table. our server Ethan was great as well as all the other staff.“

“Best pizza in town! Excellent service and the place is really well run. Very reasonable prices too. Keep it up guys.“

“Very good Chinese breakfast. Everything was delicious. Their beef roll is excellent and pan fried baos are good. I like their salty tofu curd since it is not salty and has a lot of the authentic ingredients. They did not even bother to charge for tips.“

“This side dish shop is the best I've ever been to. It tastes more Korean than Korea, and the quality of the kimbap in particular is sky-high. Keto kimbap without rice is new and healthy. This place has become a place I must visit every time I pass by.“

“I have been eating at Mandarin Taste since I was 4 years old. Since when they used to have to polaroid pictures taped to the wall where you waited for your seat. Since the shopping center was a thriving place for business.
I have been gone from the area for years now, but I came home over the summer and after a shopping trip at Brea Mall, I craved some Szechwan beef and nostalgia. Upon walking in, we noticed some small changes. The polaroid pictures are gone (mines was up there!) but everything else was exactly the same. Including the staff. They have of course aged as we all have, but I remember them in their younger years. We ordered all our old favorites. The pu-pu platter, chow mein, fried rice, and Szechwan beef. All of it tasted exactly the way it did the last time we had it. The consistency of this place is insane and much appreciated. The service was good too. I don't have any issues with Mandarin Taste and we always had great food and a good time here over so many years. Graduations, births, birthdays, and job promotions. All celebrated here. It made me sad to see the shopping center as desolate as it was. In the 80's and 90's, it was a busy place and again, many memories being there. I'm glad to see that Mandarin Taste has been able to remain and among so much change, they have been able to stay the same. Thanks for the memories. Please support this restaurant. You won't be disappointed.“

“Love Poke and this place has fresh fish and vegetables and I've been multiple times and it hasn't disappointed which says consistency - hard to find these days. It's the usual line up of choose your base: salad, brown or white rice or half/half and then proteins and add on's. Highly recommend coming out here to have a delicious poke on rice and salad.“

“Ordered house noodle, Hainan chicken, fried fish cake, and lamb skewers. The pickled vegetables was as perfect as it comes and was provided generously and consumed in its entirety. Did not disappoint. First visit ever. Will be back to try everything on the menu. Yes, it is that good.“

“We ate at this restaurant for lunch today. We were very impressed by the cleaness and their super service. The meat was very fresh, and the food bar had plenty of selections. Unbeatable price! The restaurant is under new ownership. Bros, if you live in this area, I highly recommend you to try.“

“My family and I are loyal regulars at Young Dong Tofu House—it’s hands down our favorite among all the tofu houses we’ve tried!

The restaurant is always clean, and comfortable, and the service is consistently excellent. The staff are attentive and often check in to see if we’d like more side dishes, which we truly appreciate.

Among the side dishes— the kimchi, bean sprouts, and fish cake are my top favorites—fresh, flavorful, and always satisfying. The tofu soup paired with brown rice is simply perfect. And the best part? The rice that gets crispy at the bottom of the hot stone pot can be softened with roasted barley tea to make a comforting scorched rice soup—it’s such a delightful way to end the meal.

Every visit leaves us full and happy. It’s not just a meal—it feels like comfort in a bowl. Can’t wait for our next visit!“

“Late review but I was just thinking about this place. Came here on Christmas Day with my family last year and it was delicious. Everything tasted good, lots of selection in the buffet and delicious desserts. Service was excellent. If I lived nearby I would be a regular.“

“Good Chinese Take Out. Huge portions. We've been eating at The Wok for many years. Make sure you're hungry before you go there. If u don't see what u want, ask and they'll usually make it for u. Cash only. No credit cards.“

“Best duck in the Diamond Bar, Rowland Heights, Chino Hills area. We always order duck served 3 ways - soup, sliced peking duck with thin wrap and green onions, and deep fried duck bones. While you’re there get some of the crispy pork belly too .“

“I think this is my favorite bakery that beats other korean bakeries like paris baguette and tous les jours. It's got a very homey, ma and pa vibe, and the owner always greets you with a smile and says a warm farewell. And god, I love their pastries and breads.“

“I had the daily special today: Japanese Chicken Katsu Curry with a side of vegetable egg rolls. It was so good! Their smoothies are also excellent. Very friendly and prompt staff. Thank you!EDIT: this review was written prior to the change in ownership that occurred in 2024.“

“Second time eating here when I stop by the super H Mart. Food always comes out fresh and tasty. Only positive things to say about this establishment. Steam buns and dumplings are my go to choice. Definitely be back again to try other dishes.“

“Went on a lunch date with my cousin. Thanksgiving left overs weren’t enough for us lol!

Parking: They’re located in the corner of a plaza. Free parking lot. We couldn’t find a spot within their area, so we parked near the grocery store.

Ambiance/Environment: They have a very casual, warm, & welcoming environment. They also have a small space. There’s a decent amount of seating.

Service: Once you walk in, you’ll be greeted and asked whether you’d like to dine in, take out or pick up. We decided to dine in. Shout out to Jesse & James! They were very knowledgeable about the menu, courteous, and attentive! We ordered via the tablet and paid at the register in the end.

What we ordered:

1) Combo B - We decided to share the Yupdduk (jjajang spice level). This came with boiled eggs and veggie fries and sweated rice balls on the side. The veggie fries had the perfect crisp, the rice balls tasted as expected, and the boiled eggs were cooked well. The sauce was absolutely flavorful! The rice cakes were very fulfilling! Make sure to immediately mix the cheese!

2) Boneless Chicken Feet (appetizer) - We were told this was one of their popular appetizer. We ordered this mild. Their special sauce was also flavorful! The chicken feet were cooked well. Although I’m not sure what makes this boneless bc I bit into small pieces of bone .. lol.

3) Spam Mayo Rice Bowl (appetizer) - Another popular appetizer recommended to us. We really enjoyed this! Can’t go wrong with a classic dish!

4) Fish Cake Soup - My cousin wanted something soupy. The soup wasn’t too salty. It came with a generous amount of fish cakes. Perfect for the cold weather.

5) Salted Caramel Milk Tea w/ boba (100% sweet) & Mango Green Tea w/ Lychee jelly (0% sweet) - I really enjoyed my drink! The boba was okay .. some pieces were chewy and some were hard. We were told the Mango Green Tea already has syrup, so she didn’t want anymore sugar. It was still a bit sweeter than she’d like, but she did enjoy the lychee jelly!

Pricing: The prices are fair $$, especially for the amount that you get. Everything was so flavorful, rich, and fulfilling.“

“Amazing! The food was absolutely delicious! We ordered it to go for the second time. We called in just before close and they accommodated us kindly. Extra spicy lamb vindaloo, onion culcha, achar, mint sauce- perfection!!!! See you again very soon, Diamond Palace Indian!!“

“My friend and I had a wonderful time celebrating our birthdays. The food was amazing and the owner was great with us. He made us feel welcomed. Food was delicious and green tea ice cream was so yummy.“

“Always good quality and good sized meals. Have eaten here many times and recommended if you’re a shabu fan.“

“MY FAVORITE KIMBAP PLACE SOOOO FAR! Since we've tried it, we always look forward for Sundays and having them for lunch. The beef kimbap is soooo great that I'll say it's the best tasting kimbap I've ever had. The portions are great for the price too! This place won't disappoint.“

“Loved and enjoyed eating here. The staff were so friendly and nice. Thank you Trevor and the lady (boss lady)! The food was on point!! Their Pho was real tasty and like home cooked meals. Their menu was simple and everything you’d want if craving pho or simple fried rice. Prices were ok for California and I’d come back to have me some good Asian tasting food. Thank you.“

“Oh my gosh! This is mine & my families second time ordering pho from pho Hana. I have to say it’s the best tasting pho I have ever tasted!!! This is going to be our new go to restaurant for pho for now on. ☺️👌“

“We had an amazing meal here! The seafood was the star—fresh, tender, and perfectly cooked. The Peking Duck was crispy and flavorful, and the stir-fried beef was tender and delicious. We also enjoyed the vegetables with tofu, which were light, fresh, and a great balance to the richer dishes. Everything was beautifully presented and full of flavor—perfect spot for a family dinner or celebration!“

“I always enjoy the Beef Stew Noodle and Popcorn Chicken. The service is also good.“

“Delicious food and

“Just tried this place out of the blue. Food was tasty. Service was great. Atmosphere was ok.
Oddly there was hardly anyone there. Not sure if we were there at an odd time or it just happened to be not busy. Anyways the food is definitely worth the visit.“

“Jade House Restaurant in Diamond Bar offers fast service and a great selection of affordable dishes. The staff is efficient and friendly, ensuring a pleasant dining experience. The menu features a variety of delicious Chinese and Asian fusion options. The food is served promptly, allowing for a quick and satisfying meal. Overall, it's a fantastic choice for those seeking delicious food at a reasonable price.“

“Staff was extremely attentive and friendly. Food came out quick and was absolutely delicious.“

“Great deal on the AYCE under $25 per person! You can pick whatever your tummy desires from the menu, with over 60 + items, and enjoy the made-to-order food. We started with tease/ light appetizers- rice noodle, fish shumai, takoyaki, fried chicken leg, clamsside up fried eggs then moved to carbs- friend rice, Chan's famous congee, hong kong style stried friend egg noodle, beef stew, shrimp wontons, followed by hand dipped shrimp tempura, edmame, fried scallops, fried oyster, Japanese sake clams and much more. Finished strong with house special ell rolls and a scoop of ice cream. I loved how Chan Kee adjusted the food portion to each order, since we have 3 people in the party, they would offer either 3 pcs of a small protion of the order, they want use to try everything on the menu, and not try to feed us with flavorless carbs. Our favorite item for the night was fried chicken legs; it had crispy skin, but the meat was juicy. Shrimp wontons with nothing but shrimp, we loved it so much and ordered twice. Sake clams were very fresh and flavorful! The AYCE does have a time limit of 100 minutes per visit, but it is still enough time for you to fill your tummy! We do plan to visit again and try the other items that we didn't try at dinner :)“
