50 Best Seafood Restaurants near Diamond Bar

“I don't really write reviews, but this place is really good~
The owner and employees are all friendly. Korea seems to be doing well too.
King crab, crayfish, conches, garlic bread, and scallops are all delicious.
I also highly recommend the clam chowder and Modelo Beer.
Oh, the chicken is delicious too. It tastes similar to Kyochon Chicken.“

“Tucked away in quiet street in busy Diamond Bar, behind the throngs of strip mall shops is a little Thai restaurant. The decor is calming and everything looked new.

Instead of a lunch special, I opted for a full meal and had plenty of leftovers. The Pad See You was excellent with chunks of chicken and flavorful. I also opted for the Beef Satay appetizer. However the portion was huge and dinner size at $15. I spent more than I wanted for lunch but had a second meal. Now that I’m closer to Mt Sac during lunch, I’m exploring all the options that busy Diamond Bar has to offer.

Skip the ice water and get the green iced tea. Yum.“

“We had Gamjatang and the seafood pancake, and the pancake was so good with a lot of actual seafood, and the gamjatang soup was just amazing! The flavor of the soup didn't feel artificial or sharp, and instead had a very deep but smooth flavor that I appreciated a ton. Me and my wife easily finished the meat in the gamjatang, and brought the soup back home to make fried rice and that also tasted amazing! Will be back again for more“

“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!“

“This is my go to spot. I never have a disappointing meal at this location. The place is clean and the service is fast. Our server Freddie was especially on top of his game. I didn't need to ask for a refill on my lemonade or unlimited shrimp.“

“It’s a good locally owned spot in a nondescript area of a strip mall, the dining area inside is a bit small but it has an outdoor dining area. The combos are of good value and the seafood is fresh and tasty. Service is fast and the guy who mans the joint is pretty cool.“

“Best Mexican food I’ve ever had. I’m from Australia and came to LA for a wedding. A year later and I’m still dreaming about the fish tacos and aguachile. The seafood was so fresh, friendly and quick service. I couldn’t believe the fresh quality seafood was so cheap. Hope to eat at this place again.“

“Good food and great service good for family“

“Very modern indoor environment! Have big screen with karaok songs, super relax ! And authentic Chinese style bbq food. Definitely recommend !“

“海鲜很新鲜，非常棒的用餐体验！“

“Great food and great price. Trust me, food is delicious. Very busy, which is a bit of a problem because they can't accommodate the people coming in at rush hours. Tables inside and out fill up. My wife and I get cheviche with good portions. Kids got tacos and burritos. The food was very good. Bathrooms are clean. Parking is usually full. Would get more stars really, which affects their service. No parking or place to eat makes us sometimes come back another time when there is enough space. They do have fast service.“

“The food here is amazing! Fresh fish was delicious. I had the grilled Mahi Mahi, and my companion ordered the grilled Sea Bass. I am not a fish lover, but I could rave about both. The salad was fresh and tasty. Those words don't come from me very often. The fries were quite good, and I didn't hate the fried zucchini. When we ordered the entrees, they came with two sides. They had canned soda but supplied ice and cups. The place was so clean and tidy. The staff were helpful, friendly and assisted us with ordering our meal. I will be back again.“

“First time there… my son and his friend took me. Really good food!!“

“Fiery Crab's garlic butter sauce should be illegal. It’s THAT good“

“The food was excellent. The food far surpasses the service. Let's begin with the Buffalo shrimp, which were perfectly cooked and bursting with flavor. An excellent take on wings seafood style. The seafood caldon especal was full of flavor, perfectly spices even though it has jalapeño in it bring back a sense of being on the beach. The Capechana was high quality and the delicious. The chef not only an excellent cook but took part of the service. The Michelada base alone is memorable and wanted to buy a gallon of it. The waitress was professional but needs to elevate her service skills, one attention to the client was very slow, there was no effort to explain the menu, little initiative to attend out table.“

“Super delicious amazing food and service is great“

“Esta muy sabrosa comida me encanto se las recomiendo k ballan y prueven esta deliciosa comida“

“Great food! I've been here twice and have tried the fresh shrimp and tofu spring rolls with terrific accompanying sauce, flavorful chicken fried rice, shrimp pho with delicious broth, and the lovely Lychee fruit tea! Yum! Totally coming here again... and bringing more friends. Mangosteen has a clean, modern atmosphere, primarily indoors with a couple of outdoor tables. Friendly and helpful customer service.“

“The agüachiles are tasty and the drinks (my micheladas and palomas) are refreshing. Delicious Mexican street-style snacks (pambazo that my wife ate) and the gummy snacks with chili and delicious strawberry and cream desserts. The atmosphere is cool, relaxed, and the breed is cool and friendly. Go and enjoy. You'll like it. ?? Oh, and all under the leafy shade of a refreshing tree.“

“Ceviche was fresh and tastyRaw Oysters were fresh as can be, this far inlandEven if you're not craving seafood the have cheaper foods that I recommend~Asada Taco hit and the Al Pastor tacos was solid for not being on a trompo(street style)Will eat here again!“

“I love the white fish rice on weekends. It's so delicious. White rice is also delicious and inexpensive. I love the California grilled fish rice. The shrimp rice I ordered is Southeast Asian style. The fish and chips are very tender. The grilled fish is also very tender. Perfect brunch“

“excelente servicio, excelente calidad de los mariscos y el sabor realmente sí son estilo Baja. los súper recomiendo“

“Townsent is a hit or a miss. I guess it depends who is manning the kitchen and who is taking your order. Today for lunch the food sucked. I ordered for 2 people, 1000 year pork, crispy fried shrimp, stir fried clams with ginger sauce and Kung Pao scallops. The 1000 year pork was a little chewy, normally it should melt in your mouth. The ginger clams and scallops had no flavor at all, we had to spice it up ourselves. It tasted like it was just boiled in water. The steam rice was soggy and looks like it’s been steamed way too long. The only thing I enjoyed was my hot tea. The waiter never checked on us at his own. We had to whistle him down. Maybe their food and services at night is a better hit. All I know is that I had good dining experience with them in the past. But today. It really sucked!“

“The whole food experience was amazing, I have wanted to come and dine at a seafood restaurant that would serve seafood this way. We came in a group of five people and everyone loved it. We got their big portion that serves four people For a 160 They gave us a pound of shrimps for free, and the sides for the seafood were super complementing the whole experience. I now understand why the line was so long and crazy! Food is definitely worth the weight. At least they put you on a list and keep you updated via sms.“

“I recently visited the area and had to try this spot. The fried fish was perfectly crispy on the outside and tender on the inside, bursting with flavor in every bite. The fries were golden and crunchy, providing the ideal complement to the fish. The service was friendly and efficient, and the atmosphere was warm and inviting. If you're looking for a delicious and satisfying meal, This is the place to go.“

“Best food in town and dj 👍“

“The food, service and staff are amazing. We absolutely love Cachanilla's.“

“Shout out to Baran Mediterranean restaurant. We had a superbowl/ 50th birthday party yesterday and everything was literally perfect. Food/staff/ decorations/ cake, everything was perfect. There's nothing I would change or do differently. We had a party of 80 and everyone has been texting today saying how good the food was. Go try them out, you won't regret it. Owners are pretty amazing too, super friendly and down to earth. Thank you Baran!!!!❤️“

“Muy rico excelente atención“

“great food. friendly service“

“Excellent food and service“

“Service was quick. Food was cooked to order. I ordered the two piece fish and chips. Which was two full filets of fish. Fries were frozen but okay. Fish was a little oily but I dabbed with paper napkins to soak up the excess. That and a can of soda was around 11 bucks. Pretty good price for a meal dated May 2025.“
