At EC there is also a cool place in the German Pavillion where you can get a Beck's and Bratwurst.
Italy and France both have wine tasting 'rooms' where you can try and buy.
In MGM, we like to go to Mama Melrose's for a pizza snack and a cocktail. Love those flat, fired pizza's!
Most of my favorite lounges are in the resorts, though.
Love the lounge at the Grand Floridian....very posh!
Outer Rim at the Contemporary is great for a beer and a snack and they even have the NTN trivia game! Can't beat the bar at the CG for the view.
There used to be a bar at WL where they had the greatest sirloin burger on property, but its been years since we've been there.
At BW there are numerous lounges. If you are a beer lover the Big River Grille (name?) has a beer flight that goes from light to dark from their on-property brewed beers.
So many bars....so little time!
