This is one my daughter and I go to restaurants. The food is always great and the service is always hospitable. Our go tos are the spinach dip, the hanger steak, and the ozzy rolls. The best spinach dip I’ve had to date. The steak is always cooked to perfection and tastes delicious. You can never go wrong with the ozzy rolls. Also their mango martini is great!

We had a wonderful family dinner at Coastal Flats with my husband and our four kids, and it was such a delight! Our waiter Matthew was phenomenal—so sweet, attentive, and made us feel well taken care of from start to finish. We started with the bread, which was to die for! For appetizers, we had the Tex Mex egg rolls (really good), the crab dip (okay), and the calamari, which came out a bit too sweet for our taste, but the staff was great about taking care of it right away. For our mains, I had the lobster roll with sweet potato fries—absolutely delicious! The kids enjoyed their fried chicken wings, and my husband loved his steak salad. Overall, we had a great experience, and thanks again to Matthew for making our dinner so enjoyable! We’ll definitely be back.

Coastal Flat was consistent with food being presentation taste and service. We had crab cake sliders, rockfish smoke salmon salad with fried shrimp instead of salmon. As well as the white chocolate bread pudding, please its not a traditional bread pudding, however it's still worth the calories. Our issue was our drinks, they had more sugar than alcohol. Seating wasn't the most comfortable for us.

My waiter was great and very attentive! They forgot my appetizer and the waiter checked in on me and went to grab it for us. The atmosphere is relaxed but busy with beautiful decorations. The food was okay but the bread with the honey butter wins the award in my book!!! I think these were the worse ribs, spinach and fries I’ve ever had in my life, the flavor needs to be changed. The virgin raspberry lemon drop martini was great as well.
