The atmosphere is definitely 'no frills' as others have described, but you can tell this is a hugely popular place, as it was SO busy. It was awfully hot in there, too, which I did not enjoy. However, the food was delicious! I had blackened crab cakes, three bean salad, and cole slaw. All was fantastic. We also purchased some seafood from the market area to take home and cook, which was wonderful. I agree with other reviewers that the lady at the counter could've been slightly more friendly, but she was also super busy, so perhaps that explains it.
The only weird thing was that the first three days we stopped by Ocean's, it was closed. Not quite sure why, but at least they finally opened one day while we were there on vacation!
