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 fresh seafood and drinks at Billingsgate Lighthouse Café. Today's Groupon is valid only at the Edmonton location.

Born in Alberta in 1907, Billingsgate Fish Company has bestowed landlocked humans with plates of fresh seafood for more than a century. Billingsgate Lighthouse Café in Edmonton, open since 1998, presents a menu speckled with hearty starters such as lobster bisque ($6.95/dinner bowl) prepared French style with cognac and cream. A light oil, untouched by the dark magic of hydrogenation, coats halibut fish and chips ($12.95–$16.95), and the Alaskan king crab slides onto tables alongside rice, potatoes, vegetables, and beautifully drawn butter ($39.95). Diners can opt to devour their grilled, steamed, or broiled specialties on the Café's patio or safely avoid projectile computer monitors within the dining room's confines.
