Throughout time, the hamburger bun has served as a companion for lonely beef patties and a shelter for seeds kicked off Sesame Street. Bask in the bun's never-ending hospitality with today's Groupon: for $16, you get a burger dinner for two at The Concord Grill (up to a $34.15 value). The dinner includes:

• Any one appetizer that costs up to $8.99
• Two 8-ounce burgers
Two soft drinks

At The Concord Grill, 40 different burgers command attention on a menu brimming with American fare. While lounging on the outdoor patio, diners choose from a variety of appetizers, including breaded and deep-fried mushrooms or loaded texas fries packed with homemade chili, cheddar cheese, and chopped onions. A bevy of burger flavors beef up the meal, such as the Hawaiian burger, which comes dressed in sweet-and-sour sauce, pineapple, and a bacon hula skirt. The A-1 burger gathers heapings of mushrooms and onions with a steak-sauce lasso, and the Greek burger stands prominently chiseled in a black-olive-and-feta-cheese toga. Thick bites of burger can be washed down with two accompanying soft drinks, which, like the front half of a donkey costume, are bottomless.
