Best meal EVER??--our very first WDW meal at the old Papeete Bay Verandah. Had a Seven Seas Cocktail, Pigs and Prawns entree, scallops in lime and coconut as an appetizer. All with a great view of the Castle and entertainment by a 3 piece combo and a hula dancer. And I remember almost all of it, tho it was over a quarter century ago!! (9/1975 to be exact)
These days tho, it's any meal at V&A!!
Worst--probably Liberty Tree, when Mrs. U's chicken was served functionally raw on the inside.
