The hamburger, America’s national meal, has always been served during Independence Day cookouts and the competitive-eating portion of presidential debates. Sink your teeth into patriotic eats with today's Groupon: for $7, you get a combo meal for two at Del's Charcoal Burgers in Richardson (a $15 value).

Del's Charcoal Burgers has been grilling flavorful patties and brewing up frosty mugs of homemade root beer since 1957. Lock arms with a date and trot down to this friendly haven of hamburger, where you can each lock lips with the contents of a combination plate, which includes a sensationally savory sandwich, a mound of finger-licking french fries, and a choice of soft drink. Tour 2 of the 50 states by sharing a texas cheeseburger, bursting forth with flavors of hickory, smoky bacon, jalapeños, and cheddar ($7.50), and the california chicken sandwich ($7.50), luring in mouths with slices of avocado, swiss cheese, and rumors of gold. The philly cheesesteak explodes with cheesy charbroiled flavor reminiscent of the city's famous meat sculptures ($7.50), and vegetarians can sink their gentle fangs into the grilled heart of a charbroiled veggie burger ($7.50).

Note that Del's Charcoal Burgers is not open on Sundays.
