8PM would be early for me. 10PM would be typical. 11PM would not be unheard of. Today I ate a late lunch at 3PM so had salad & cheese at 11PM. The funny thing is if I happen to eat at 5PM or 6PM when my neighbors take me out for dinner, I don't really get hungry later in the evening. I eat 3 meals a day. I live on the east coast, but am not sure what difference that makes. Are you seeking time zone trends?
