Market House is not cafeteria. It is counter service. Disney lists places as "Quick Service" or "Table Service." Most people on the boards have come to label quick service as "Cafeteria" or "Counter".
Plaza Inn is cafeteria. You go up to the window, ask for the pasta dish/chicken/beef, they plate it and hand it to you. You go by the salads, pick one out and put it on your tray, go get a soda, put it on your tray, then go pay for it. Same with Zoccalo. Get your tray, go to the burrito section, order your burrito, they make it and put it on a plate, go to the salads, pick one out, grab a drink and go pay.
Hungry bear is Counter. You go to the cashier, say "I want a cheese burger no sauce, fries, and a drink", you pay, walk up tot he counter and they will hand you the tray.
Way back when I was in school, you ate in the cafeteria. You got a plate and were served hot dishes, salads, fruit, milk, etc... Same in college. My daughters say it is still like that in our area.
