✨️Exceptional Dining Experience at Coastal Flats✨️ – Gaithersburg, MD.
From the moment I walked through the doors of Coastal Flats, I knew I was in for something special. The hospitality, atmosphere, and service were truly outstanding from start to finish.
Josh, the manager, personally came to our table to introduce himself—an intentional touch of professionalism and warmth that immediately set the tone for the evening. His leadership was clearly reflected in the smooth flow and excellence of the entire team.
Our waitress, Brook, was nothing short of incredible. Her kindness, attentiveness, and genuine hospitality elevated our experience and made us feel truly welcomed. She is a wonderful representation of top-tier customer service.
I ordered the mahi dish, and let me just say—this was by far the BEST mahi I have ever tasted. Perfectly prepared, full of flavor, and cooked with clear mastery. Compliments to the chefs and kitchen staff for such phenomenal craftsmanship.
From the entrance staff to the kitchen team, every part of this establishment operates with excellence. Coastal Flats has undoubtedly earned a top spot on my list of favorite restaurants in Maryland.
Highly recommend! 👏🏾🍽️✨

Great place for happy hour. Been there for dinner plenty, but the bar at happy hour is the best atmosphere and the bartenders are all great. Food is also solid. I'd do anything accept the crab cake, its just always super wet no matter how it's cooked. Everything else is really good.

Absolutely amazing. Went here for the first time since I've been in the area for work, our server, Eric, was phenomenal. Took the time to listen to our requests and really took care of us. This was quite the experience and the best service we've ever gotten and the food itself was splendid.

This is my favorite place at Crown. The staff is attentive, the food is well seasoned and the cleanliness is excellent. My favorite is the shrimp roll because of the sauce that it comes which is delicious.

We came for a “Mommy & Me” birthday lunch. Even with a reservation, we waited about 30 minutes to be seated. My mother has diabetes, so the delay and the very sweet dessert weren’t ideal.
Her Filet Mignon looked plain and tasted a bit bland; my fish was on the salty side. They later brought fries, but by then the moment was gone.
The food was average, the service lacked warmth. It wasn’t overpriced, but it felt under delivered. Not the kind of experience we expected for a birthday lunch.
