Well tbh when I went it was their 5th anniversary! So a decade ago
My parents took packed lunch and we sat in the picnic area...but with it being October I would think that would be quite a bad idea lol!
I remember there being a Main Street and past that was a few restaurants...I think maybe The HardRock cafe and a place you could have your meal with Micky and Minnie. I'm sure there were other outlets too, like McDonalds, but I think it was mainly fast food while we went. As far as I can remember the ice-cream was really expensive - about £1.10 each back then
We never ate in any restaurants while we were there so I'm not much help am I sorry
I never actually went into Paris, but my parents went for my mums 40th a few years back and they said if you wanted a decent priced meal to go to the student area of Paris - but to be careful. Obviously the closer you are to the Tower and The Arc de Triumph the more stupid the prices are.
I will try to get some more info out of my mum and dad about the museums and I know they went up the tower but it was quite expensive.
