Was there 2 weeks ago. OK for Minnesota. I think they don't care about the checks as long as you don't want to split everything. they seem to be OK putting what you got on whatever check is handy. 10:30 no wait 10:45, 45 min wait
I was there Sunday at 11:30. It was good, really busy, larger groups had to wait (they had quite a few tables of 6+) so maybe call ahead? My suggestion would be to have everyone bring cash and contribute equally, all dishes get passed around.
