34 Best Seafood Restaurants in Costa Mesa

“Sushi Shunka is our go-to spot for celebrating special occasions and also our fave sushi spot in OC. Located in a strip mall at the corner of E. 17th Street and Tustin Avenue in Costa Mesa, the restaurant specializes in authentic sushi and Japanese cuisine. "Shunka" means "Flavor of the Season", so they of course select their fish depending on the season and in addition to customer favorites. The sushi chefs are veterans and the wait staff are polite helping to provide an unforgettable dining experience to their customers.

I highly recommend sitting at the sushi bar and ordering one of the omakase options. On our recent visit, I ordered the Chef's Omakase which included 10 pieces of sushi including sea bream, Japanese sea bass, mackerel, amberjack, toro and bluefin tuna among others. The sushi is always top-qualify and practically melts in your mouth. I have a big appetite so I also supplemented my meal with a toro hand roll, blue fin tuna hand roll and fried Hamachi Kama. Everything is made to order and is so oishi! Having said that, this is fine dining so expect to pay a high price but know that it’s worth every penny. As I mentioned before we only visit on special occasions, so I’m already hoping we’ll have a reason to celebrate again soon!“

“I ordered the fish & chips. To go. It was absolutely fantastic tasting and fresh. I’m most definitely going back and highly, and I mean highly? Recommend this. Place!“

“As someone who travels frequently and eats out regularly, I can confidently say this place is a hidden gem! They have the best shrimp and fish tacos I’ve ever had—the seafood is always fresh, and the flavors are incredible. Their chipotle salsa is perfection!

The staff here are always so friendly, and the service is great. We've been coming here for years and have never been disappointed. They also stay open late, which is a huge plus!“

“My first time here!
I was greeted warmly and all my questions were answered!
I ordered the seafood combo and it was not only delicious but it was a very generous portion of shrimp, fish and calamari mixed with veggies and was served on top of rice.
The lady who brought my food was very courteous, said my name is Angelica and came back and checked 2 times to make sure I don't need anything else!
I will definitely eat here again soon.

“We made a reservation for our Anniversary celebration and the restaurant went above and beyond to acknowledge our special occasion. Starting with a congrats from the hostess, to the waiter, to a nice card, to a gift card for an app or flatbread, they made our meal and outing special. We have eaten here often, and order pick-up often as well, and it is one of our favorite restaurants for the quality and value. Service and food are always excellent, as was this meal.“

“Authentic, great service, fun staff!“

“Could not ask for a better dinner spot to end the day!!!“

“Oysters are always super delicious and fresh! The list of oysters is extensive and ever changing. The salads are so filling and the clam chowder is the bomb! Staff is always friendly and the service is great.“

“Came here for the first time in years. I got a wet burrito and it was delicious. At first I was very skeptical because of the price but once I got my food in front of me and started chowing down all skepticism and doubt went from my mind. This was a rare case where I thought the price of the food was appropriate for the portion size. I would recommend the carne asada burrito covered in green sauce.“

“1st time there for lunch with co workers. Great, friendly service. The food was out quick and was very delicious. Would definitely go back. Thank you.“

“Collage provides not only a high quality but a visually appealing space for a wide selection of dining options. You really can't go wrong with any of the food options, and it's convenient that everything is close together in one area. In fact, it makes for a great meeting place for friends or gatherings!“

“For me, new flavors. I will be back.“

“The best poke I've ever eaten. Poke Tiki-Newport has it's own very unique flavor not found anywhere else. Definitely one of my favorite places I have to visit everytime I'm in town.“

“Baja grill chiken burito.“

“First time visiting this restaurant.
We ordered a Machete, 7 Mares and a Campechana.
7 Mares missed a little flavor.
The cocktail as well as the Machete were delicious.
Service was outstanding.
DJ was performing that night, it was good.
The DJ took the chance to interact with us, asking us for songs to play.
Overall, we had a great time.“
