Stuffed deer antlers, a large canoe suspended from the ceiling, and carvings of bears surround diners at Bill's Pub North. The northwoods seeps indoors at the venerable pizza place, which exhibits the idiosyncratic decor of a lodge. The wood-grained eatery first established its novel dining room more than 50 years ago, when its founder and namesake converted a garage into a roadside pizza joint. There, Bill and his wife, Pat, devised the double-decker pizza that still emerges piping hot from the kitchens at two locations. Both locales exhibit the same relaxed setting, in which families can scarf double-decker slices and freely toss peanut shells to the floor or out windows at mounted policemen.
