When I saw the thread title, I immediately thought of the 1967 Roger Corman LSD film with Peter Fonda and Dennis Hopper that preceded Easy Rider, and wondered what the food connection could possibly be. (Shows you what a difference frame of reference can make.) But now that you describe it, I saw the preview for
this The Trip recently, and immediately decided it was a must-see. Few previews have that effect on me; I'm glad the film is as good as the preview made it look.
