One of Benjamin Franklin’s last theories was that taking in a good view while eating aids both in digestion and in the ability to squeeze milk out of coal. Prove him half-right with today's Groupon: for $12, you get $25 worth of fresh seafood and drinks at Rusty's Seafood and Oyster Bar in Cape Canaveral.

Rusty's Seafood and Oyster Bar occupies a nautical-themed waterfront house, with life preservers hung from the ceiling and fishing trawlers right outside, reflecting a menu full of shellfish, fresh fish, and other fruits of the sea. Expert oyster shuckers sling raw or steamed bivalves by the platter ($9.25) or bucket ($31.99), accompanying them with a range of raw bar accouterments. Jumbo lump crab au gratin ($10.99) bakes sweet chunks of crab meat with four cheeses, served stuffed inside a hot sourdough loaf. The eatery's signature encrusted mahi mahi ($18.25), a savory slab of fresh fish baked in a secret blend of spices, pairs well with a salad ($5.99–$11.99). Customers who visit on Backward Day can start with homemade key-lime pie ($5.99), a sweet-tart treat piled with pillowy meringue.

Rusty's flow of good cheer spills from its rustic, wood-clad interior onto a sprawling outdoor deck, and a full bar features eight draft beers and four specialty frozen adult beverages. The restaurant's "come as you are" policy accommodates patrons whether they are dressed in tank tops or Royal Canadian Mounted Police uniforms.
