I assume you mean Folly Beach?
-Taco Boy for tacos, beer and margaritas
-grab a burger at Surf Bar. They have great burgers. I just saw that they were named one of the South's best bars by Garden & Gun mag. I think they were one of the best bars to take your dog too. Ha!
-Tokyo Crepes is a cool food truck that has savory & sweet crepes and usually sets up shop for breakfast and lunch. Check out their facebook page.
-Venture over to Johns Island and have brunch, lunch or dinner at Fat Hen. You won't regret it. Great cocktails, French & Southern fusion (can I say that?). Everything is delicious and locally sourced. It's a nicer place, casual but not beach casual.
We were there last year. Taco Boy was pretty good, we ate there a couple of times. I've discovered as I've gotten older that I really don't like the beach. They were nice enough to let me hang out there for an hour or so and drink iced tea, and watch soccer while the rest of the family hung out on the beach.
Snapper Jack's was pretty good as well. Friendly service and decent food. Nothing outstanding at either place.
When we were there they had a ban on alcohol at the beach, something about a drunken brawl a week or two before we got there. I think this held the crowds down.
