I have more problems with their website than I do with the certificates. Last time I had a bunch of stuff in my cart for a 90% sale code and it kept crapping out on me, and then I couldn’t get back in to order them before the sale ended. Just as well, since I had 4 Cafe Revo certificates there, and it was a week before they closed down.
Speaking of which, Restaurant.com still has Cafe Revo on their site. I emailed them right after they closed to let them know (and link to the WSB news story and Revo’s site), and they replied on 10/21 to thank me and said they’d take it off ASAP. 3 weeks later, it’s still on there. So if you are buying a certificate to a restaurant you don’t know well, you might want to make sure it still exists.
