Actually, the best Pot Roast at WDW is at Boatwrights. I would never think of having Pot Roast on vacation but the waitress convinced me to try it, now I'll never go to Boatwrights without thinking about the Pot Roast.
PS: Boatwrights is at POR and if you go when the entertainer is in the lounge it makes for a great night. The entertainer is very family friendly and fun. Some of the best entertainment on property.
