Liberty Tree is good if you are in the mood for a Thanksgiving style meal, it's one of the better restaurant Thanksgiving meals I've ever had.
We've always had good meals at Skipper.
Honestly, BOG is a decent deal if you are going to eat the Filet which is very good. A Filet at any restaurant is typically around $30.00 add in a $10.00 app and a $10.00 dessert with a Drink and you are only paying around $5.00 extra for the atmosphere versus just about any other restaurant in WDW. It's decent classic French food, I don't know why people complain about it outside of maybe they are eating something that isn't worth the money for their entrée.
