The Diner's Deck is a collection of restaurant coupons with the fit and feel of a deck of playing cards. Each of the 52 cards, redeemable at a participating New York City restaurant, contains a description of the venue and a coupon for $10 off. The Manhattan-centric decks come in three neighborhood flavors: Midtown, Downtown East, and Downtown West (Uptown and Brooklyn versions are in the works for 2006). Like any coupon collection, the decks are a gamble. Use three cards, and you'll break even. Use every card in the deck, and it's a $490 value. But, let the cards collect dust for a year like that stack of Bed, Bath, and Beyond coupons you've been saving, and, well, you lose.
The Diner's Deck is $29.95 from cityshuffle.com.
