To subvert grumpy monarchs, angry medieval youths scrawled condiment graffiti like "Fran Tanner has plague" or "The king is a jerk" inside their hamburgers. Dig beneath lettuce to bring history to light with today's Groupon: for $5, you get $10 worth of hamburgers, sandwiches, and drinks at Big Larry's Burgers in Valley Center.

Big Larry's selection of burgers and sandwiches is as diverse as the types of teeth in a shark's mouth. The Big Larry ($5.34), a 3/4 lb. patty with mustard, pickles, lettuce, onions, tomatoes, and cheese, is available with double ($7.84) and triple patties ($10.34) for truly heroic burger enthusiasts. With chili, two types of cheeses, jalapeños, and onions, the Stinger ($4.04) is the perfect way to test taste buds' structural integrity. Opt for a BLT ($3.19), Philly cheesesteak ($5.09), or barbecue beef ($4.09) to satisfy classic sandwich cravings. While most burger joints would be content to merely serve freshly cut fries ($1.94 for a medium), Big Larry's also offers cheese tots ($2.64), fried okra ($1.79), and fried pickles ($2.59) for those looking for a change of pace in their burger sidekicks. Six kids' meal combos (served with fries or fruit, a small drink, and a dessert treat) are also available for $3.06 each.

With more than 25 years in the restaurant business, Larry and his wife Heather created a burger mecca that should be a rite of passage for any true comfort-food fanatic. With black and white checkerboard floors matched with a red, white, and blue color scheme, the interior of Big Larry's will remind you of '50s spots where gals in poodle skirts sipped milkshakes and tamed wild Slinkys that slunk secretively behind barstools and beneath tables. Let Big Larry and friends ease your anxieties with a celebration of mustard-drenched Americana.
