I've been using these all over town for almost two years now,once we went to a place that said they changed owners and weren't accepting them anymore,if this happens you call restaurant.com and they credit you so you can get another restaurant.At Disney I've bought certificates for House of Blues,Garden Grove,Bluezoo,Il Mulino and over at Celebration the Imperium Food and Wine.I used Garden Grove and Imperium about 2 weeks ago,both places were great but I think I enjoyed Imperium more, they have very good sandwiches there.We went to Garden Grove about an hour before they closed and there were maybe 6 other tables,there was a lot of choices in the buffet but with the place getting close to closing they weren't replacing some of the items.At House of Blues we also went pretty late after 10pm and apparently after 10pm they cut their menu down to burgers,sandwiches and salads they also have appetizers and drinks at half price,we opted to save the certificate for when they have the full menu,we just ate 3-4 appetizers each half price and a dessert.Next trip I think we'll use Bluezoo.Trust me I don't think you'll have a problem using these certificates as who knows how many people have bought these since these restaurants went on there.
