“Call ahead to order takeout. The porridge are delicious, dried shrimp rice rolls and pineapple bun are delicious 😋 🤤“

“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!“

“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!“

“I’ve been ordering from Thumbling through Uber Eats for a while but finally came in recently with my partner and I’m so glad we did. The food is incredibly tasty; we didn’t leave a single leftover. The xiaolongbao dumplings are just as juicy and flavorful as the ones from Din Tai Fung, which says a lot. Noodle delicious and garlic string beans are yummy.

It’s great to have an option this good so close by, and at a really solid price point. The tables were full when we arrived, so there was a bit of a wait, but nothing unreasonable. Service wasn’t overly personal, but they did check in on us, kept our water refilled, and the teas came out very quickly.

Overall, it was a great experience. I’ll definitely be coming back. This place has officially become one of my favorites.

Note: Parking can be very challenging. Definitely avoid parking near the car entrance—you will get stuck.“

“I’ve been to this place several times, and it never disappoints. First of all, the service is excellent from the moment you walk in, to being seated, to placing the order, everything is smooth and efficient. The food also comes out very quickly.
Most importantly, every dish and drink I’ve tried has been delicious. I’ve eaten here many times and have never been disappointed. Highly recommend!“

“All the food tastes pretty good, especially the kung pao chicken. It all came out pretty fast, except for the wonton soup. Everything also came for good prices. The fried chicken was a bit oily though, and a few of the dishes were salty too, like the fried calamari and fried chicken. We ordered from the lunch special choice which was one appetizer plus two pretty large plates. Overall, it was a very nice meal.“

“Features: Came to this restaurant yesterday，I lived in Guangzhou for 20 year，Finally find the best rice noodroll in LA，it taste very authentic as the original location in gz.Super delicious rice noodle roll and congee place ?Fresh rice noodle roll，terrific beef，and chili sauce with garlic is impressively fresh （Highly recommend try it with nice noodle if you like spicy）?The congee also quite good，love their preserved egg with pork congee?Definitely love this place and will come back.“

“Took our friends to try out the food, and it was really good. Good portion, not oily and tasty. We ordered 3 dishes and it was enough for the four of us. The fish with stir fried veggies had a similar sauce to the chicken, both dishes were good. The eggplant dish was amazing. We also ordered 3 bowls of rice, and had left overs to take home. Bang for your buck!“

“We go here for a quick & simple breakfast. The pick your own combo is a good deal: porridge + choice: lo mai gai (sticky lotus rice) + drink. The BBQ pork cheung fun is smooth with the right amount of chew and you can see it made to order through the glass sometimes. The staff are friendly and attentive while it does get busy on weekends and lunch rush. Joe the manger will check in to see how’s things are going which is rare in HK style restaurants but appreciated in any setting.“

“My son ordered from the big menu (not lunch special) to customized the taste to be a little bland with sauces on the sides. I am recovering from illness. William helped us a lot; what best dish to order and how it's cooked! He's very attentive to our order and did really great! He's very knowledgeable and worked with the cook to give us the best meal! My son was greatly impressed with the service, he said he like to go back.“

“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!“

“Monday 5/12/25 Dinner with my son. Enjoying a wonderful meal; father & son night out. The foods were good. There are a large selection of dishes on the menu. It would take a person to visit numerous times to try all the dishes they offered; it’s good if you are a local.

“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.“

“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.“

“The steak dinner and the rack of ribs.“

“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!“

“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.“

“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.“
