Like a high quality straitjacket, a high quality sub roll keeps its lettuce, tomatoes, and magicians from easily escaping. Keep both hands tied up with today's Groupon: for $7, you get $14 worth of subs at Lenny's Sub Shop.

Lenny's fills stomachs across the nation with a menu of hearty sandwiches stuffed with sliced-to-order deli meats, chicken and tuna salads made from scratch, and a specialty hot-pepper relish made from whole diced cherry peppers. Regular size subs measure 7.5 inches and contain a half pound of meat and cheese, and large subs stretch to 15 inches, pack a full pound of foodstuffs, and exert a gravitational pull on coastal tides.

A range of specialty hot creations include the french dip, a savory comingling of roast beef and swiss served with a side of au jus ($6.25 for a regular; $9.95 for a large), and the hot italian, a zesty, meaty marriage of ham, genoa salami, prosciutto, capicola, and provolone doused with oil and vinegar ($6.25 for a regular, $9.95 for a large). The sandwich shop's authentic philly cheesesteak adheres to tradition by packing in slices of grilled onion, Philly-style beef and swiss american cheese and cooking it using nothing but kite-induced lightning bolts ($6.25 for a regular; $9.95 for a large), and less adventurous appetites can be sated with other delicious options including kids' meals, chips and cookies, and salads.
