Concierge.com's insider take:
Don't be distracted by the other ice cream shops on the Vineyard; there's a reason why Mad Martha's has lines out the door all summer long. The ice cream, made at the Oak Bluffs establishment but also sold in Edgartown (7 North Water St.; 508-627-8761) and Vineyard Haven (20 Union St.; 508-693-5883), comes in more than 20 flavors, including a killer black raspberry and a nutty, not-too-sweet pistachio. Avoid the sundaes, though, unless you're lucky enough to score one of the few tables: They're too gloppy to eat standing up.
Open mid-May through late October.
