Restaurant.com certificates are just awesome. Although they do have requirements (your meal has to meet a certain amount most of the time and 18% gratuity is added to amount before discount) when they have coupon codes you just can't beat the savings. For example, they have a code valid now for 80% off, so $25 gift certificates are only $2. Type in your zip code, browse through the list of restaurants and voilà, savings! The coupon code is: STEAK.

Bon Appetit!
