A high-protein diet can help 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 $30, you get $60 worth of steak and seafood at Chuck's Cellar in Waikiki, Chuck's Steak and Seafood in Ko 'Olina, or Chuck's Steak House in Waikiki Beach.

Menus and pricing may vary slightly between Chuck's Restaurants's three locations—Ko 'Olina, Waikiki, and Waikiki Beach—but all three meld upscale cuts and catches with a casual atmosphere, obviating the awkward sight of a tuxedo jacket thrown over a Garfield-print aloha shirt. Open lava-rock grills send meaty aromas to gallantly guide diners to the all-you-can-eat salad bar offered with every entree. On any given night, an array of veggies might be escorted by soupy sidekicks such as seafood chowder, french onion, or tomato vegetable. A herd of aged USDA Prime–grade steaks graze with the teriyaki sirloin, which soaks for 48 hours in a house-made marinade before reaching your plate. Chuck's fish-finaglers hook the catch of the day from local waters, presenting a line of island fish such as hebi, opah, or ahi, served grilled or sautéed (market value). Several variations on surf 'n' turf unite feuding sectors of the culinary kingdom by wedding prime rib (starting at $28.75) to lobster tail (market value), and sirloin (starting at $24.50) to scallops ($28.50). Most meals range $20–$40.
