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

“Warm welcome, kids friendly food tastes yum.“

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

“Read my post it's the best around“

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

“This is the first time I was able to try authentic northeastern Chinese breakfast in California, and it really satisfied my cravings. The food is just like it is back in China and very delicious. The menu is short and simple which is my favorite since that means they specialize in specific foods. Must try for some authentic and delicious Chinese breakfast! The staff are very friendly too.“

“Highly recommend if you love din tai fung style cuisines without waiting 2hrs and breaking your wallet.
Their dan dan noodles with rice noodles was savory, with that lovely peanut base sauce.
Their Crab & pork xiao lou bao is super delicious. Their skin is thin and the soup inside just fills your mouth. Honestly i think it's better than Din tai fung for that alone.
The beef tomato noodle was filled with thick, tender beef chunks, and the diced tomato was actually sauted with savory seasoning.
You can see many locals come here to enjoy excellent quality comfort food.
From Ordering to being served was a matter of minutes. Great for limited lunch break people!“

“I recently visited Ma’s Banchan and was honestly impressed. The banchan tasted just like homemade food—fresh, balanced, and not overly salty. You can tell a lot of care goes into the preparation. The portions were generous for the price, and the staff was very friendly. It reminded me of the side dishes my mom makes at home. I’ll definitely be coming back!“

“Very authentic in atmosphere, food, and service. I got the chirashi bowl and it was absolutely delicious. Fresh. Excellent texture. I was such a huge fan of their sushi rice as well! They have lunch specials that I clue miso soup and salad. Highly recommend coming here for lunch. Your whole party must be there to be seated and it gets busy (always a good sign).“

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

“My favorite local Vietnamese restaurant. I always get their number 18 pho which is brisket and well done flank. This place is the only place around me that serves amazing food while being very affordable. Service is always welcoming and room is always filled with happy customers.“

“Always mine and my family's favorite poke place! Although Jimmy's Poke across from the Walmart is a lot closer to us, Mr. Poke is just top notch, may I say the GOAT. Jimmy's doesn't compete with Mr. Poke's freshness, portions, and atmosphere; Jimmy's is way too expensive for just 2 bowls of poke, and has gone downhill ever since they opened. Jimmy's menu was inconsistent and had quite a few stuff out of stock last time I was there in 2025. However, Mr. Poke has really stepped up with newer decor, quality consistency, and even adding on a stamping system for rewards that'll make us loyal customers come back for more.

Although not fully packed, their patrons sure have increased compared to the first time I tried them in 2020, where there was practically no line and only 1 employee. Not a long wait, but it can get a small line even on the weekdays, so it'll depend. But it's always clean and quiet with a few tables and seats. In addition, they added another employee to the line when I visited today 6 years later, demonstrating how they've grown in reputation.

Ultimately, I'm glad to see a small business growing and getting the recognition it deserves, so I highly recommend them to keep it up! 👏“

“The best chinese-American food in the entire southern CA and perhaps in the entire CA!
Fantastic Chef, friendly service and a friendly atmosphere! I come here at least once a week to get my Fish and black bean sauce and any other dish that I want to have!“

“The meats were pretty decent, the ponzu was properly made, plenty of chopped scallions, sufficient amount of fresh veggies including 茼蒿price was reasonable for AYCE, and the eating area was roomy and comfortable. We tried its house spicy base, which was a bit spicy but good and the clear bone broth.

We haven’t been to this plaza for a couple of years and seemed that after HMart opened its Chino location, this plaza has been quite empty.“

“This is the place we went to have a quick bite when we moved to Diamond Bar 8 years ago and then we found so many other places to eat and almost forgot this restaurant. Recently we visited this place again, the menu is same except price a little higher. The quality of food are same but now they gave you disposable chopsticks instead of re-usable ones in the past. Other than that, not much change, always busy but the waiting time is tolerable. I like this beef BBQ rib combo with seafood tofu soup and they are good. They don’t have steak knife but so provide a pair of scissors and a small pair of tongs so that you don’t have to eat BBQ beef with just chopsticks.“

“I was in town and looking for a new place to try. Thanks to Yelp, I found Noodlemii nearby. We headed over for a weekend dinner and didn't have to wait long for our group of two.

We tried a variety of their menu items, including the black pepper udon ($12), yellow curry ($11), beef skewers ($6.50), and a Thai iced tea ($3.50). Food came out pretty timely and everything was really good! Good portion sizes too.

Bonus points for being part of the Diamond Bar Open Rewards program. Good amount of parking in a shared plaza. Will be back to try more of their noodle dishes next time!“

“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.“

“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.“

“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.“

“Very good food and me and my family absolutely love taking it home“

“We usually order a whole duck to take home so I’m not sure how they are at the restaurant, but this place has DELICIOUS duck. Some of the best I’ve ever had. Savory, moist, and extremely flavorful.

My family also adores the soup here; we always add extra to our order. While their cold dishes leans more pricey, we INHALE the tofu skin cold dish!

Highly recommend getting duck from here!“

“正宗台灣味～店家也很客氣“

“chilis was very very good tonight“

“Those little food stalls inside H Mart are the best, especially when there’s an older lady who’s been there forever—always kind, warm, and makes the food taste even better. That fish cake soup hits different, especially on a cold day. Simple, salty, comforting…total Korean soul food.“

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

“The buns here are stuff to the brim with filling with chives, glass noodles, wood ear mushrooms, and pork. Its a great quick meal to have after a long day because of how large the bun is. The frozen dumplings from here are also very generous in filling and are best boiled as soup or pan fried. The taste is meaty.“

“very bad customer service.i like before. so.i was there because.we lives in Corona California.my brother lives in walnut.so.i thought go for dinner.we was waiting for start soup.the girl Asian waiters gave very bad service .she ignored.so.we call nice arabic language man.may be manager.so.she came.sorry i forgot.and after us the boy came.she.left everyone and she take the order first.lauging.and... she took extra one order charge.she asked you want Receipt. my husband say no.after.he fell doubt.so she.gave Receipt and run.quick.my husband chack Receipt extra charge.so.my husband call the nice man for chck Receipt. she charged extra.she was nervous. and don't give any strong answer.say I don't know.

“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. ☺️👌“

“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.“

“Came here with an Indian client. Had the dal Chana and the spicy bread. I always get that when I go to Indian places. Very filling and tasted good. Spicy the way I like it. Made me sweat but I love it. I finished the entire thing. They keep it on a heat warmer with a candle so stays hot. Hours later I’m still full“

“Everyone was super nice and attentive. I couldn't take pictures but everything tasted great. We ordered Khandavi, bhel puri, kachori with aloo sabzi and Chana bhatura and a jaljeera to drink. Our 2 year old daughter also ate everything.

Though it was a little spicy for her, she enjoyed the food and we were able to get some raita for her. The owners gave her a laddoo too as we were leaving as she wanted a sweet before we left.

Super amazing service, everyone was happy to help and we just beat the crowd for lunch so we got served pretty quickly. Food quality was excellent as was the taste. Finally some good Punjabi food!“

“Everything we ate was very good. The porridge was very good. This week. Sour fish was very good. The Krispy pork was very very good. The chicken feet were very very good. The spinach was very very good. The egg for young was very very good. The pork chow mein was very very good. Oh all the service was average for a Chinese restaurant, one dish. There was a confusion on, and they brought the wrong one, but they corrected it quickly and we also got shumai that we’re very very very very good. When you look around the restaurant, you would not be able to know whether you were in Hong Kong or Singapore or the Philippines or Shanghai or Beijing, or anywhere else“

“I visited this restaurant for the first time with around 15 members of my family, and every single one of us loved the food! The quality was excellent, the portions were generous, and the prices were very reasonable.

Everything we ordered was fresh, delicious, and full of flavor. The staff were welcoming, and the overall experience was wonderful.

I highly recommend everyone to give this place a try. If you visit once, you’ll definitely want to come back again. This is one of the best dining experiences we’ve had, and we’ll certainly be returning!“

“Delicious food and
Good service
Beautiful atmosphere 👌
I had lunch buffet was very fresh and they give fresh bread tandoori chicken samosas and vegetables pakoras. After customer walk in restaurant.
Everything was worth it.“

“I've come here for years now, my dad is a regular and they know him. I love the tea they serve during dinner, always warm and refilled multiple times. We always order walnut shrimp, egg drop soup, Chinese broccoli with oyster sauce, Hong Kong style fish fillet, and ginger/garlic lobster dish. I would also recommend the duck! It comes with soft white buns and crispy colorful chips, very moist and delicious! Would always come 2 to 3 times a year.“

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