France, at Epcot, either sitting at a table outside the little bakery/cafe or on the edge of the fountain. With all that Disney has to offer, you know what my kids, ages 8-15 request, every trip? "We're going to get to sit and eat bread and cheese in France, right?"
Also, right outside the Star Trader's gift shop in Tomorrowland, there's one of those raised flowerbeds, or something, and some benches, and the TTA is going overhead, and it's the perfect place to sit with a Mickey Bar and just...absorb.
We also used to enjoy having our morning coffee at the Counter Service in Adventureland, I think it was called the Tiki Terrace or something, there were tables with umbrellas and it was one of the few counter service places opened early that had coffee. But cramming Aladdin's carpets smack in the middle of it ruined the view, and made things WAY busier.
