A diner's oversized booths and oversized pies have long been a beacon of hope for teens dumped after prom and frowny clowns looking for new novelty-sized props. Take refuge in the crispy crust of an old-fashioned eatery with today's Groupon: for $7, you get $14 worth of breakfast eats, lunch items, dinner classics, and more at Denny's on Granite Lane in Sioux Falls. For more than 50 years, Denny's has been stifling rumbling stomachs with a menu of around-the-clock breakfast plates and classic American dinner entrees. Morning munchers and meat-eating vegetarians can chow down on the Ultimate omelette, a three-egg amalgamation sporting sausage, bacon, fire-roasted peppers, onions, and other edible accessories ($8.69), while those afraid to handle meat without bread gloves can order up a French Toast Slam and use brunch food to make a pretend lunch sandwich at dinner time ($7.79). Denny's offers a warm family-oriented atmosphere where griddled grains and cured bacons meld to energize hungry patrons for a day at work or for an afternoon staring contest.
