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, sandwiches, and pasta at Black Tuna Bar & Grille in Norfolk.

Black Tuna's chefs masterfully create a menu of decadent seafood, pasta, and American dishes amid a modern atmosphere glowing with white and bluish purple light. Mouths can let go of clarinet reeds or poorly written birthday cards to begin a culinary seaboard adventure with an order of blackened-tuna bites ($10) or a culinary land jaunt with a duo of mini cheeseburgers ($7). Carb cravings evaporate in a bevy of pastas, such as the Norfolk scampi—soaked in a silky white-wine sauce to inebriate five sautéed Gulf shrimp, sundried tomatoes, and a bed of tender linguine and mushroom pillows ($15)—and the chicken penne ($13). The kitchen team also drizzles Cajun rémoulade across seared chunks of blackened tuna to create the restaurant’s eponymous delectable ($19) and molds luscious lumps of crabmeat into crispy cakes ($21 for two).

Sleek black chairs and high-back booths lay between bold red walls and tiled ceilings in Black Tuna's dining room, creating a modern atmosphere for diners or robots pretending to have digestive systems.
