Restaurant.com regularly offers gift certificates at dramatic discounts—you pay $10, say, and get a $25 coupon to one of the hundreds of listed restaurants. But for a 99-hour sale starting on 9/9/09, they're going 90% off; enter the code "ZOO" at checkout, and you'll get $25 at a participating restaurant for just one buck. No A-listers, but you'll find decent spots such as Cafe Asean, A. J. Maxwell's Steakhouse, Boucarou, and about five hundred more. [via Travelzoo]
