A high-protein diet can help to build muscle, which comes in handy for fighting off a shark that is also on a high-protein diet. Take a bite out of the circle of life with today's Groupon: for $25, you get $50 worth of seafood and steak-house fare at The Oar Steak & Seafood Grill in Patchogue.

The chefs at The Oar cast a wide net over land and sea, catching generous portions for a menu of inventive seafood and steak-house fare. Dip forks into entrees such as the crispy roast duck marinating in a maple-whiskey glaze ($22) or the 8-ounce fillet in a red-wine reduction ($29). The seafood fra diavlo—a medley of mussels, clams, shrimp, and scallops—swims in a light sea of marinara ($28), and the pan-roasted swordfish breaches over an isthmus of vegetable risotto and lands in a bed of seaweed salad ($25). A rotating roster of live bands ensures silverware stays clinking against glasses.

Steaming entrees served to tables clothed in white waft aromas upward toward a vaulted ceiling supported by rich wooden beams in a nautical dining hall. Stepping through delicate french doors, guests are transported to an ample patio enclosed inside a delicate latticed fence. Eyes soak in gently rolling waves, the sun setting behind the grandiose masts of sailboats, or maritime jousts for parking spaces in one of The Oar's docks.
