Hi Michelle!
Generally speaking, there are no Disney Dining Plan specific menus. Basically, you can order anything off of the menu as long as the item is listed as something for one person. This causes some confusion because some menus do offer something, such as an appetizer, that is meant to be shared and a person can't order that via the Disney Dining Plan. Also, some restaurants offer, for example, a three course prix fixe meal Sometimes guests can select that via the Disney Dining Plan and sometimes they can't; in the cases were a guest can, sometimes no substitution of any kind is allowed.
However, since you mentioned a specific incident on your last trip, I would be happy to research that restaurant if you send me more information.
By the way, you can get more information on the various
Disney Dining Plans here. I hope this helps! Write back with more questions
