Living4Fun, I am not familiar with the Supper Club Book but if it details Supper Clubs in WI, Hob Nob may be in there. I love your idea of doing a Supper Club tour but I would probably start at Coerper's Five 0'Clock and be passed out by the time I left Dillard's in Minocqua.
LOL ...my intent was to do a tour but take a year.
This is the book..... couldn't find an index online. Wisconsin Supper Clubs: An Old-Fashioned Experience Hardcover by Ron Faiola (Author) I actually have the book but I'm not at home and don't remember if Hob Nob is listed.
