I agree with
@roselark. I was there last year with a vegan. We had no problem eating at any restaurant. They all accommodated her even though there were no vegan dishes on the menu. Actually we went to the Hoop De Doo Review which is a fixed menu and the chef came out and asked her what she would like for dinner. Like roselark he was excited to make something different for her. Her vegetables looked delicious. We all wanted it. If I listened to the people on this thread we wouldn't have eaten there because they have one menu and only accommodate allergies. Disney is very good at adjusting for vegans/vegetarians/pescatarians. Not just allergies.
So to
@LSUfan4444 I suggest you make what ever ADR's you want and let the waitress/waiter know your wife won't eat the meat and ask what they can do for her. If you want to do it ahead of time there is a phone number to call for Disney dining but I can't find it at the moment.
