Fresh Seafood at Alonzo’s Oyster Bar Key West

Alonzo’s Oyster Bar Key West has been serving the island since 1947, delivering the ultimate waterfront dining experience on the historic A&B Marina. Surrounded by water on three sides and open daily 11AM–10PM, this lively seafood restaurant offers everything from casual lunches to sunset cocktails and dinner overlooking the harbor. Crowds gather for share-worthy seafood towers—the Treasure Chest and the Shipwreck—stacked with chilled oysters, crab legs, lobster tails, shrimp, and rotating premium selections straight from the raw bar.

Guests can begin with island favorites like handcrafted conch fritters, coconut-crusted shrimp, and Caribbean-style tuna nachos before warming up with classic New England clam chowder or bold island-spiced conch chowder. Fresh oysters remain the star attraction, showcased raw on the half shell or baked with toppings like Key lime garlic and spinach Parmesan. Entrées span coastal classics and Cuban-Caribbean inspirations, including blackened local fish sandwiches, succulent lobster rolls, sesame-seared tuna plates, seafood pastas, hearty platters, and satisfying non-seafood options.

From watching the famous marina tarpon feeding from the deck to enjoying tropical cocktails during a spirited happy hour, every visit reflects authentic island flavor and scenic harbor excitement. Flip-flops, sunglasses, and a craving for fresh seafood fit right in at this iconic Key West seafood restaurant overlooking the boats and bustling waterfront life.
