It's been forever and a day since I bought a Restaurant.com gift certificate. When I first found the site in 2008, the site was pretty … eh. Their selection of restaurants in my area was limited and worse was that they never seemed to change.
However, when I saw they were selling gift certificates for 80% off, I took another look and found that they had greatly improved on their selections. Most franchise restaurants don't accept the certificates, but pretty much every mom & pop type eatery by me does. They all have a spending requirement, for instance a $25 gc has a $35 requirement, but you'll still be saving money ($35 meal – $25 card + $2 cost = Final cost of $12)
Anyway, punch in your zip code and have a look. Maybe you'll find a place you love or somewhere that you've driven past a million times and never eaten at. When checking out, use code MEAL for 80% off your purchase through April 30.
