Just beware that the fine print always allows the restaurant to refuse the certificate for any reason. That happened to me once, at Drunken Fish in St. Louis, AFTER we got done eating the meal. I followed all the details, and presented the cert at the beginning of our order.

The manager refused the cert at the end of the meal because we had some items that were happy hour specials. He said happy hour was a "promotion," and that the certs could not be used in conjunction with any other promotions. My beef was that he refused them after we finished our meal. I would have liked to know this at the beginning, since we probably wouldn't have ordered quite as much stuff.

Restaurant.com customer service was unable to help us out, other than offering a free $10 certificate (min $30 order). Not satisfying, since I wanted a refund for the cert.

Otherwise, I've probably used a dozen other certs over the last two years without problems.

Sometimes you luck out when the restaurant also participates in rewardsnetwork -- that program is automatic, and the restaurant has no idea you're a member.

Maybe next time I'll order the certs through ebates or the aadvantage shopping portal for some more savings/points.
