Good wraps and pina coladas, going there for Thanksgiving dinner after the Turkey Rod Run this year, inexpensive, lots of local retired folks, so you know it's a good buy

Good for oysters, peel and eat shrimp, clam chowder, dark and cool inside, kind of a relief when it's super hot out.

By the lighthouse, didn't have a very good meal there, but watching the boats and the sunset on the intercoastal is awesome.
There's a place called The Wreck on the river, can't find website, great view, good salads, watch the sliding glass doors if you have little ones, ds ran right smack into it.
Hope this helps a little. Have fun planning. Where are you staying?
