I've used these and they do work. Infact, with a no expiration date I had one that is no longer good on the website still left. I called and they credited my account with a $25 gift certificate to replace the one that is no longer good with them. You do have to read all the rules and you do have to comply. Some examples are good for dinner only, not good on meal specials or alcholic drinks, or not good for take out. One biggie is that usually you can only use one certificate at a time per month. Also, multiple certificates will not be honored at the same table or even different tables if you are talking with one another, etc. Just be careful and follow the rules. Try it once and see how it goes. Some certificates sell out at more popular places. There's like a limited amount of these certificates per place per month.
