Culver's in Wisconsin. butterburgers and frozen custard. not to mention buttered buns, and buttered soda, which the people here call pop. crispy onion rings, fresh red onions. we like. and our whole lunch was $9.58 Culverisms: every bite of a culver's butterburger is like getting a hug from grandma; our frozen custard is so good you'd think our spoons are silver; every smile starts with a sip (of their own root beer, also available as a float).
