Actually my parents found something very interesting at one place .... they did a "take time off, travel north america" trip last year, and found this place ... name escaping me ... I think it was something like Hot Tossed Buns. Well, they walk in ... and sit down ... and not only were the portions amazing, they had two things. Instead of peppiers, they had people who walked around, with the side dishes of the day, offering you more and more, if you wanted more at any time, you got it.
