Guests stroll up from the beach to sit on a bamboo barstool underneath a tiki roof. Nurse your drink and, with any luck, a college of dolphins will swim by before long.

Marshside Mama's Daufuskie Island, South Carolina

The scene : "Our bar is like Canterbury Stories ; there's a bit of everything," announces bartender Tyler Gerow of the honky-tonk Marshside Mama's.

Even though it is just a 45-minute ferry ride from Hilton Head, the ferry does not often run, so that the crowd is mostly local boaters. They rock out to live bands on weekends and follow the lead of owner Beth, who's known to yell out, "No whining, just dance. ".
