My dear, at 4 in the morning, people are just as drunk and hungry here as they are in America. Only here we have only the Autogrill on the autostrada, and if you're not close to the autostrada, yer fuct. However, sometimes there are some panino stands that made AWESOME greasy, heavy shit late at night after hours. Sausage with grilled peppers and onions on a bun with mayo and ketchup. Ho-ly shit. Sometimes you just can't wait to drive all the way home for something to eat.
But I should say that if we are at concert festivals longer than a day, we always bring our own pasta and stuff,
