Food is so good! Shared crab & shrimp fritters to start. (Comes w 3) They were so good, so much meat & no filler. I got their grouper special (they also have grouper fingers on the menu all the time) & a side of mashed cauliflower. My friend got crab cakes & she said it was really good. I got... More

This restaurants is part of the Great American Restaurant chain in metro DC. I have yet to eat a bad meal in any of the brands. The service is always good. Yes, it's is pricey, but, the food is not the usual fare, it's fresh, and the quality is high and consistent

Went for a Saturday lunch with a girlfriend. Got seated right away (there was a wait when we left around1:30). I had the pecan trout with mashed cauliflower which was very delicious and a nice size. The atmosphere was very clean and bright. Service was good.

Coastal Flats trains their staff well, and has reliable and tasty food too. Crab and shrimp fritters with a wonderful corn salsa and broth, could munch on them all night. The fish entrees were cooked perfectly with amazing cauliflower puree...The kitchen turns out food fast, so if you want to linger, take your time ordering. Call ahead seating is highly... More

The prices were fairly high especially for lunch. My lobster roll was good and the wife enjoyed the Ocean City salad and her Oktoberfest beer but over $50.00 for lunch with no appetizers or desserts, well....

I think this is a great non-chain neighborhood restaurant. They have a wide variety of food types. I really like the Hong Kong Sea Bass and the Chicken with Havarti Cheese sandwich. They are really know for their Ozzie Rolls which are like the bread version of mini donut holes. The wine list is great and the ambiance of the... More

My wife, kids and I go to Coastal Flats at least once a month. It's probably our favourite restaurant in the Fairfax area. The food is excellent. We always start with the shrimp and crab fritters, then I go with the hickory grilled salmon, medium, not medium-well! My wife goes for the pecan crusted trout. Their shrimp role is also... More

Went to this new offering in the new Crown Center area of Gaithersburg, Md with another couple. Glad that we had reservations since people were being told at 7PM on a saturday evening about a 1+ hour wait. We got a table near the entrance very soon after our reserved time of 7PM. Food offerings were very limited and fairly... More

The title says it all, great decor and wait staff. Coastal Flats, has drawn the yuppy crowd and the younger crowd. The facts are, this restaurant serves petite portions of food listed on their dinner menus. When I dine out and try a new restaurant, I expect a reasonable size portion for Mid $20's for a dinner. I ordered Veal... More
