Yay!  I'm so glad that after not visiting a couple years Dotty's is still the excellent burger joint that I remember.  For about $7 bucks you can get a perfectly cooked medium rare beefy burgers with some gourmet ingredients.  I had their goat burger with goat cheese and basil.  Nice combination.  Their cheese curds are awesome.  Fries are a pass - they're the frozen kind.  Overall a great cheap eats place that I'll visit every time I'm in Madison
