We sat on the patio. Atmosphere was peaceful, it rained while we were out there and it didn’t get on us. Food was really tasty, got the crab cakes and lobster roll and bread pudding. Thank you for the great service!

Coastal Flats was an easy walk from my hotel at Rio, and from the moment I arrived, I felt welcome. As a solo traveler, I appreciated being seated at a great table. The lighting was bright yet intimate, with little table lamps creating a lovely ambiance. Top 40 pop filled the air, and the beautiful dockside mural made it easy to imagine I was dining seaside instead of in Downtown Crown.
I ordered the hickory-smoked fish special featuring grilled mahi mahi, cabbage slaw, tomatillo verde sauce, and a tostada over black beans. The portion was generous, and the fish was beautifully cooked: glistening, flaky, and tender. The verde sauce had just the right amount of spice, complemented by creamy avocado. My only critique was that the slaw was a little abundant and hid some of the delicious elements underneath.
The chili pineapple margarita had a great balance of flavors, though I would have enjoyed a little more chili. And how could I forget the complimentary bread? Warm little pillows that paired perfectly with the whipped herb butter. I limited myself to one to save room for dinner, but it took some restraint!
Amanda, my server, made the experience especially memorable. She brought abundant positivity, knew the menu well, offered great recommendations, and was accommodating and attentive throughout the meal. She made dining on my own feel comfortable and enjoyable.
If you haven’t been, I highly recommend it. If you have, I bet you understand why!

This is an amazing restaurant. The staff are super friendly and food is great. Goat cheese salad and Brussels sprouts are exceptional!! I will definitely go back when I come back to town.

Usually I love this place and always get take out. But the portion of the already small lobster bisque this time was ridiculous. It’s normally full. I spent $9.00 for a half filled bowl of soup and I’m extremely disappointed. The fries were also incredibly salty this time.

On Labor Day, my family and my cousin's family visited this spot to take advantage of a Resy benefit from Amex plat. We had a reservation for eight and were comfortably and a bit squizzedly seated at a booth. For appetizers, we shared the Ozzie rolls, frites, and crab bisque. Unlike the crab soup at The Grove, there was no visible crab meat in this bisque, but given the lower price point, that was completely understandable. For the main courses, I had the trout, my son ordered the lobster roll, and we also shared the Jumbo Fajita. The lobster roll was easily the standout dish of the day! The fajita came with plenty of mushrooms but was a bit light on the steak. Overall, the restaurant is very spacious and serves solid, decent food.
