Through 1/12, take 50% off dining certificates at Restaurant.com via code CHOW. For example, a $25 gift certificate, which sells for $10, is now only $5 and a $10 certificate, which sells for $4 is just $2. Better yet, the code will also snag you a free $10 Restaurant.com certificate. Obviously, not all restaurants participate, but there is definitely a good selection to choose from. Just be careful to read the fine print as many restaurants exclude alcoholic beverages, weekends and other things.
