Dim Sum Restaurants near Diamond Bar, CA

“Came here on a Thursday for some dinner to-go. There were around 2-3 customers when I dropped by around 7pm.

I got a garlic veggie and a crispy noodle. Both were super delicious. The veggie sauce made it just right seasoning. Would definitely come back for some dim sum next time“

“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!“

“Very authentic Hong Kong food — feels just like home! The dishes taste really local, and the service is honestly the best I’ve ever had at a HK restaurant in the US. Prices are great, portions are generous (we actually ordered too much and had to take some home 😅). Definitely a spot worth dropping by to try — highly recommended!“

“Whenever I come to visit my family in the area, Get Sum Dim Sum is where I come for amazing food. The flavors and textures are incredible. My favorite savory dish is the shrimp and leek dumplings and for dessert, the lava buns. If you want to find comfort food in Southern California, this is where you should go. Since I live far away, I do not get to eat here as often as I would like so I’ll have to live vicariously through you. Enjoy!“

“Yummy Yummy! We're so glad that we have a delicious XLB place close to us. They have XLB (Xiao Long Bao/steamed pork dumplings) for BOGO promotion. Yes, buy one, get one free. We ordered their juicy pork Xiao Long Bao ($12.99 for 9 pieces), and they also gave us another order for free. (so we had a total of 18 pieces for 2 orders). We also ordered braised pork. The flavor of the pork was marinated well, and the texture was perfect, soft and tender. Their cucumber with garlic was also delicious.
We like their food so much and hope they do well in Walnut.“

“There are ample parking spaces around this restaurant. The pan fried daikon cake is very good, so is the spicy lo mien. We have also tried shumai, bean curd roll, and preserved egg and pork porridge, which are about average. The Portuguese egg tart is very flaky and tastes pretty good!“

“They carry a variety of different types of dim sum, always fresh and friendly staff“

“Best authentic dim sum in this area -hands down. They offer special dim sum dishes like scallop shumai in xo sauce and abalone shrimp shumai in xo sauce to name a few. Both were delicious! Serve the traditional dim sum dishes as well which are amazing! Great quality and value. Highly recommend them and tell them I sent you! Cheers!“

“Delicious food, fast and courteous service; we tried various entree and they were all amazing!“

“I’m a student at Cal Poly Pomona, and our club often hosts Chinese cultural events. For our Mid-Autumn Festival celebration, we got food from Miss Sichuan — it came out super fast and was sooo good! Everyone loved it 😋 Definitely ordering from them again!“

“Food 4/5 - Ordered beef chow fun, chinese sausage/diced broccoli fried rice, braised crispy tofu w/ three delights, and crispy pan-fried whole flounder. Beef chow fun and the fried rice were delicious, both dishes have very good “wok-hei”. Crispy pan-fried flounder was also delicious, good crispy outside fry with the fish still being soft. There’s some soy sauce beneath the fish, but I’d like it to be served on the side so you can dip your fish pieces. Braised crispy tofu was good, tofu texture was very soft and the 3 delights (shrimp/fish fillet/octopus) were fine.

Price $$ - Price is good for the portions that were served. The plates might look small, but they have depth.

Service 3/5 - Service is average, we needed to flag down a server to refill our drinks.

Atmosphere 4/5 - Interior is good with Chinese themed decor.

Overall - Had a pleasant experience and would visit again.“

“The food is amazing! Such a selection of great flavors. Dim sum is on point and the Teddy bear iced coffee is a perfect finish to a great meal.“

“My family have been here yesterday，It was awesome!
The food is delicious, and the service is excellent! Bruce was the best server — very friendly, attentive, and his English is fluent, which made the experience even better. Highly recommend!“

“Absolutely delicious food and outstanding service!
From the moment we arrived, we felt very well taken care of. I asked the lady at the front desk if it was possible to have non-spicy food, not even pepper, and she was incredibly kind and accommodating. They immediately agreed to modify the recipe and prepared everything without any spicy ingredients, which I truly appreciated.
The food was fresh, flavorful, and perfectly cooked. You can tell they really care about their customers and are happy to adjust dishes to make everyone comfortable.
Prices are typical for Anaheim Hills, so nothing unexpected there.
One small note: on Sundays the restaurant is open from 11:00 am to 9:00 pm, and it looks like this might need to be updated on Google.
We will definitely be coming back. Highly recommended!“

“Very nice place with fresh seafood“

“I LOVE DIM SUM KING MASTER. Best items are the haim suk gok, siu mai, and their rice noodle rolls which are different then a lot of other shops and more thin. The rice noodle rolls are made fresh. A must-try is the pineapple buns which are also freshly made and are always very warm and fluffy. Last recommendation, is their thai tea. This is my go-to place for dim sum. Support small businesses!!“

“If you're craving dim sum, this place is definitely worth a try. The dim sum menu is solid, offering a decent variety of dishes that satisfy those midday cravings. The food quality is good overall, flavorful, and filling. However, when it comes to dinner time, the experience takes a bit of a dive. The dinner menu isn't particularly impressive, and the foods lack in flavor. I wouldn't recommend coming during dinner time.
The service, unfortunately, leaves a lot to be desired. The staff can be a bit inattentive and, at times, even rude.“

“This Cantonese restaurant offers a very solid and authentic dining experience.

The menu focuses on traditional Cantonese flavors—light, clean, and well-balanced, letting the quality of the ingredients shine. We ordered several classic dishes and everything was executed well. The roasted meats were flavorful with crispy skin and not greasy, the steamed dishes were fresh and properly seasoned, and the stir-fried dishes had good wok hei.

Ingredient quality really stands out, especially the seafood, which was fresh and well prepared with no off-flavors. Portions are reasonable and the pricing feels fair compared to similar Cantonese restaurants.

Service was attentive and relaxed, and dishes came out at a comfortable pace. The dining area is clean and comfortable, making it a good spot for family meals or casual gatherings with friends.

If you’re looking for traditional, no-frills Cantonese food done right, this place is definitely worth a visit.“

“Ordered takeout during the holidays and the food was ready to go at the agreed upon time. The staff were very thoughtful and kept the fried dish uncovered in the to-go bag to maintain the crispiness. After the car ride home, it was still crispy and yummy. Overall the food was pretty good and a hit with most of the people. Some of the dishes were a bit salty, but that was expected from this type of establishment.“

“It is a very professional and authentic Chinese restaurant. The food selection is very rich. There are various Chinese dishes with different flavors to choose from. I like barbecued pork buns and rice rolls, as well as chrysanthemum tea. There are many traditional Chinese people here, and some white people. The decoration of the restaurant is great, with Chinese characteristics, and it can also host some parties and celebrations.“

“Mama Lu's Dumpling House in the City of Industry is the perfect place for some delicious Chinese and Taiwanese cuisine, and it's easy to see why. The restaurant has a lively, family-friendly atmosphere that makes you feel right at home. My recent visit was a perfect example of their reputation for serving up generous portions of quality food. My family loves this place for their delicious yet super cheap eats!

A classic is their Juicy Pork Dumplings and Soup-filled Shu Mai; these dumplings are the stars of the show, living up to their name with a flavorful broth and tender filling. For something with a kick, the Spicy Wontons were a definite highlight, with a rich, aromatic sauce that had the perfect amount of heat.

The main courses were equally impressive. The Salted Fish and Chicken Fried Rice was a savory and well-balanced dish, while the Salt and Pepper Tofu Fish had a wonderfully crispy exterior and a soft, delicate inside. They were having a special where this dish was only $9.99!! The Beef Wrap was amazing, a delicious green onion pancake filled with tender beef and fresh veggies and loads of sauce! For greens, we chose their Sautéed Baby Bok Choy, a simple but perfectly prepared vegetable dish that provided a nice, fresh contrast to the other rich flavors.

The service was prompt and attentive, and our food arrived quickly. Mama Lu's lives up to its reputation for serving authentic, delicious food that is perfect for a group. I can't wait to go back and try more of their extensive menu.“

“This review is for hosting a WEDDING banquet at Happy Harbor in Rowland Heights.

I helped plan a wedding here. I have to say it was tough at first because they do not have a designated event coordinator. There was a lot of back and forth. What was really helpful was the main guy spoke English, Cantonese, and Mandarin!

Ultimately you need the wedding date and the number of guests. You choose the menu, napkin color, and table cloth color.
Extras: They had two microphones with stands and a small stage for the sweetheart table. The audio system only reached the main room. There was a big screen in the main room to play a slideshow. The backroom seemed to have their own audio and two screens. We could not figure out how to connect the two, so the guests in the back room had to come out to the main room to see/hear what was going on.
-The lobby is large. Good to set up welcome table.
-There is a small private room behind the fish tanks. This was where vendors took their breaks.

The wedding I helped plan had just under 280 guests, so they took up the main room (20 tables) as well as the back room (7 tables). Some tables had 11 seats but same amount of food. Because of the number of tables, there was no dance floor.

I heard compliments from many guests that the servers were efficient and helpful. They served wine properly.

Overall I would recommend Happy Harbor for a large event.

Side note:
Happy Harbor gave us a contact of a guy who did white seat covers with ribbons. That guy only had a two-person team and did not finish all 270 seats. In fact he stopped just under 20 tables and did not get any in the back room at all. He also set up with the spandex seat covers, which is not what the bride wanted.“
