For a casual dozen and drinks, I’d skip Pearl & Horn unless you want a more polished cocktail-and-dinner setting.

Best pick: The Oyster Bar — it’s built for exactly this: Gulf oysters shucked to order by the half-dozen or dozen, plus beer and cocktails. Go early if you want to keep it low-key; it turns more dinner-oriented later.

Pearl & Horn is still a good choice if you want craft cocktails, wine, and a nicer raw-bar atmosphere—but it’s more date-night than casual. It’s at 1504 W. Intendencia St. and is currently listed open 4:30–9 p.m. Sunday–Thursday; 4–10 p.m. Friday–Saturday. Menu / details

Other casual options

• Salty Pearl Raw Bar — a relaxed Perdido Key choice at 13470 Perdido Key Dr.; especially good if you want oysters with a beach-side/drinks vibe. Details
• Peg Leg Pete’s — best for very casual beach energy; expect a wait at peak dinner time.
• Atlas Oyster House — downtown and more social/upscale-casual than a traditional oyster shack.
