When I teach the segment of my Law & Entrepreneurship class on franchising, and I use Culver's as a case study, I inevitably draw a comment from a student who tells me that Kopp's Frozen Custard is better. Culver's is a franchise, and Kopp's remains a small family business with just three stores in and around Milwaukee. Tonight, for the first time, I had the opportunity to eat at Kopp's. The hamburger was outstanding -- one of the best I have ever eaten. The custard, on the other hand, was a bit too warm (soft) for my taste. I tried both vanilla and Rocky Road (which had those cheap, hard mini-marshmallows ... yuck), and although I am no custard connoisseur, I have a slight preference for Culver's.
