Seafood. The former Upper Deck at Boston’s on the Beach is now the more upscale, seafood-oriented spot. The menu ranges from familiar to slightly more inventive, from a classic lobster bisque and crisp-tender fried clam bellies to to rock shrimp pot pie and baked grouper topped with blue crab. The cinnamon-dusted beignets are puffs of amazingly delicate deep-fried air and should not under any circumstances be missed.
