Growling stomachs can hamper stealth operations, spoil belly dances, and, in extreme cases, induce dogs to attack. Quiet whimpering tummy tones with today's Groupon: for $15, you get $30 worth of American fare at Stonefire American Grill in Elgin.

Inside Stonefire, diners can memorize a menu filled with fresh seafood, succulent steaks, crisp salads, and more. Lunchers can make sure their swallow muscles still work by chewing into lobster queso dip with flatbread ($10) or eating the fried green tomatoes, which spring from local land to be covered in goat cheese and roasted-red-pepper gravy ($7). Six gourmet sandwiches entice eaters to linger for the philly dip's thinly sliced prime ribeye ($9) or the pickled ginger, wasabi aioli, and thai fire chili that highlight the grilled-ahi-tuna sandwich ($9).

Combining comfort foods with sophisticated flavors, dinner entrees such as Low Country crab cakes in a fresh mango-green-tomato salsa ($18) and the 12-ounce ribeye with stuffed potato wrestle each other for table space ($18). Diners also discover their better half with the roasted half-chicken, a dish that's chaperoned by a medley of roasted veggies and a lemon-chicken jus ($14). Seafood selections flung from nearby boats include salmon, mahi mahi, and ahi tuna, served in a choice of sauce and side ($18 each). Thanks to Stonefire's bar, guests can complement both lunch and dinner with a beer, a glass of fermented grape juice, or a long, refreshing swig of ice water.
