You will Love it!! We don't make any dinner reservations on the nights we do the Festival - and we basically "Eat around the World". The food is offered in sample sizes, basically the size of a small appetizer and the prices range around $3-4. After about 4 or 5 of them (the price of an entree at one of Disney's table service) you are quite comfortable - then you can work on dessert!! And don't forget to sample the wine. Here is a link to a website that has Last Years Booths as well as prices!!
