We really enjoy The Plaza. It is a must do for us every trip. It is simple food, soup, snadwich, salad, but it is always well done and we enjoy the atmosphere. The tomato soup is really, really good, and I like the burger there as well as the club. I am not a ruben fan, but DH says it is good. The desserts are FAB!
We have done CRT lunch and are going agian this year for dinner. Here, you are paying to dine with princesses in the castle. It is NOT a $50 meal, but the food is not bad. We enjoy it.
We have done CP for breakfast and thought it was realy good. Lots to choose from and good character interaction.
We are trying Tony's this year. The reviews on it are mixed, but we have several friends that really like it.
Don't know about LTT. The "meat and potatoes" aspect of it never appealed to me. I cook that at home all the time.
