Putting a man on the moon was briefly considered mankind's greatest achievement, until Neil Armstrong invented sliced bread. Savor civilization's finest creation with today's Groupon: for $5, you get $10 worth of gourmet sandwiches at Smacky's on Broadway in Spokane Valley.

Under the direction of veteran restaurateurs, the staff at Smacky's on Broadway erects more than 40 different bread-and-meat sculptures dolloped with a signature homemade mayo and house mustard sauce. Diners grab hold of such specialty deli sandwiches ($4.75 for half; $6.95 for whole) as the pesto roast-beef melt and the avo-albacore melt—tuna on an english-muffin bed beneath a perforated blanket of swiss cheese, the favorite sleeping arrangement of Victorian children. Monte cristo and roasted-garlic turkey paninis, blackened-chicken caesar wraps ($6.95), and a rotating medley of soups ($2.75–$3.95) round out the menu selection. Walls decorated with vintage magazine covers and crumbs culled from the moustaches of 19th-century presidents provide a rich backdrop for classical sandwich scarfing.
