Take 50% off Restaurant.com dining certificates with coupon code DELICIOUS through Thursday 5/22. The dining certificates are printable credits that you take to local restaurants. The restaurants give the credits to Restaurant.com, who then sells them for less. For example, a $25 certificate normally sells for $10 but is now only $5 with the 50% off coupon code. Obviously, not all restaurants participate, but there are more than you think. Also, be careful to read the fine print as many restaurants exclude Saturday, alcohol, and other things. The code also applies to their Dinner of the Month club.
