So, it will spoil your supper. But the only time there's never a wait at Four Seas Ice Cream in Centerville is weeknights between 6 and 7. (You could start with a sandwich at the shop, if you like. PB&J, tuna salad, and cream cheese with olives are among the classics on offer.) The 75-year-old scoop shop is a Cape Cod landmark, open from the weekend before Memorial Day until the weekend after Labor Day.

WHAT TO GET: Vanilla's the most popular flavor, and for the daring, there's Vanilla Chai. Penuche is based on the classic fudge flavor with pecans.
WHEN TO GO: Once school lets out, summer hours are from 9 a.m. to 10:30 p.m., seven days a week.
