Like the earth, a sandwich is made of layers and gathers its strength from its meaty core, which pushes condiments toward the crust to erupt and bury fingers in deliciousness. Let rivers of flavor run with today's Groupon: for $15, you get a five-meal punch card valid for one entree—sandwich, salad, or breakfast item—of up to a $7 value per visit at Grace Street Grill in Norfolk (up to a $35 value).

The sandwich-smiths at Grace Street Grill stuff authentic Amoroso rolls shipped in from Philadelphia with succulent cheesesteak to concoct a smorgasbord of savory sandwiches. Triumphant slices of grilled beef parade down the pepper-steak philly sandwich beneath a shower of sautéed green pepper and onion ticker tape. In the kitchen, cooks wash a slab of grilled chicken in barbecue sauce to create the barbecue chicken philly; saucy and cheesy philly fries topped with chicken or steak emerge from the fryer crispier than a deep-fried autumn leaf. Grace Street Grill also caters to the most important meal of the day with an arsenal of breakfast sandwiches served on a choice of four breads with a rousing bugle reveille on the side. Veggie-craving diners can also opt for the tao salad, a zen combination of tomato, avocado, and onion levitating above romaine lettuce.
