I just got two amazing deals at Restaurant.com! I got four $25 gift certificates to the Armadillo for $8! Now it is usually $10 for each $25 gift certificate, but I have a great sister-in-law who shared a coupon code for the site with me (80% off your restaurant.com purchase) so I got each $25 gift certificate for only $2!
This website has great deals for small local restaurants. However, I found hardly any big chain restaurants on the site. This is great for getting good deals at those little whole in the wall local places. It was fairly easy to use as you just type in your zipcode and a mile range (15 miles from the zip for example). It then pulls up all of the restaurants for that area. You can then refine your search by restaurant type, food type, etc. The only issue with this is you have to use the back button until you reach the original search page if you decide to change the refined parameters.
