I had two places, the first, is in the Mexican pavilion, it's the Mexican cantina outside, if you can grab a seat right up against the railing, grab some food, and a margarita, it great.
The other was in France, pretty much the same, get up against the railing, there are some round tables that you can sit at, get some French cheese and pasty from the bakery down the ale, and some French champagne, also very nice.
If I could make a suggestion were ever you sit, wait for the crowds to die down a little, then take a walk around the long way (if on Mexico’s side go tords Canada and visa versa) the pavilions are almost deserted marking it a nice chance for night time photos in front and around the pavilions. The other added benefit is the busses and monorails have cleared out some making it less of a wait, and crowded transport.
