TOD: Most burgers we haven't out aren't as good as the bison burgers we make at home. In Detroit (well, Dearborn) there was Miller's Bar which had some mighty great burgers. I think it's still around. For the fancy burgers, there's a really nice version in San Francisco at Marlowe and The Cavalier. Plain is great, but good cheese, bacon, and caramelized onions all make fine toppings.
