A gourmet grilled cheese sandwich is a grownup take on a childhood favorite, much like coffee-flavored ice cream or full-contact peek-a-boo. Relive a classic with today's Groupon: for $4, you get $8 worth of gourmet grilled cheese sandwiches at GrrChe.

GrrChe's chefs rove around Baltimore in a mobile truck to dole out heat-kissed breads slathered with medleys of five gourmet, gooey types of cheese and fresh ingredients. Cruise through the menu, which is populated with toasty meals, including The Caribbean grill, a heat-sealed treat laden with mango salsa, swiss, and honey mustard ($6.50). Molten cheddar melts over pulled pork and macaroni ($7.75), and double-cream brie spills over Maine lobster for a meal as gooey as a love letter written by a fifth-grader. A complimentary pickle spear and a choice of chips or an apple round out the hunger cessation. Considered the most socially acceptable way to be friends with a truck, following GrrChe on Twitter also allows people to track the location of the grill wagon.
