Lively La Super Rica (Main and Bay Sts., 631/725-3388, $13) specializes in Mexican dishes made with healthy ingredients, and giant-sized margaritas. Not surprisingly, it’s a favorite with twenty-somethings.

A classic seafood shack appropriately named The Dock House (1 Long Wharf, 631/725-7555, $14) sits among bobbing yachts right on the pier. Lobsters clamber about in a clawfoot tub in the corner of this tiny establishment barely big enough for the four wooden barrel tables and counter. It’s worth the wait. But if you don’t want to wait, you can wander with your lobster roll or fish and chips to nearby park benches.

The Dock House is also an excellent spot to pick up the freshest of seafood for your own clambake as it doubles as a fish market. Check their chalkboard for prices.

For great views of the yacht basin while dining, check out the Dockside Bar & Grill (26 Bay St., 631/725-7100, $16), serving lots of seafood, along with other American favorites, in a cavernous former American Legion Hall with an enormous patio.

The classic spot for dining in Sag Harbor is the red-brick American Hotel (25 Main St., 631/725-3535, $28), which despite its name has a European feel and serves French-American cuisine. The restaurant has won numerous awards for its 46-page wine list.
