After properly cooking a lobster, its once-brown exoskeleton turns bright red, letting chefs know that it's both ready to serve and profoundly embarrassed for showing up without pants. Make a meal of deliciously mortified seafood with today's Groupon: for $15, you get $30 worth of seafood surf and turf and more at Castaways in Webster.

Nestled on the shore of Lake Ontario, Castaways serves an expansive menu of seafood, pasta, chicken, and steak dishes. Scenic sunset dinners commence with starters such as mussels steamed in a white-wine-garlic sauce ($8) or crispy egg-battered artichoke hearts ($9) that fulfill one's daily requirement of edible love. Creole-style blackened tilapia with sausage and peppers ($18) arrives over a bed of rice, and the shore platter woos eyes and mouths with its cavalcade of shrimp, scallops, crab cakes, and haddock ($24). Lunchtime noshing quiets stomach grumblings with seafood nachos ($12), comprising a pile of fried tortilla chips with shrimp, crabmeat, and Newburg sauce, and 13 sandwiches—such as the hoagie-hugged lobster roll ($13.90)—fill the crustacean-shaped void in diner's souls.
