"King Tide Fish and Shell, on Portland’s waterfront, has a robust raw bar menu, including oysters on the half shell, served with cocktail sauce, fresh horseradish, yuzu mignonette, and lemon. Enjoy them as part of a seafood tower or at happy hour, daily 2 p.m. to 5 p.m. at the bar, when a half-dozen goes for $12." - Krista Garcia
