One of my favorite websites to find great offers is couponmom.com. I recently seen this on their website:
Save 80% on Restaurant.com certificates Pay only $2 for a $25 gift certificate with code SANTA
I checked the website out and found a lot of great restaurants in my area. It's simple, just enter your zipcode and you will find restaurants in your area. You can also filter your results by categories such as cuisine, atmosphere type, and etc. Check it out.
