Not your personal favorite??? You're the one who sent us to Sobelman's in the first place (which, by the way, we loved). So, if Sobelman's isn't your fave, what is? Fred's in Burlington doesn't count because...well...because they're in Burlington, not Milwaukee. Kopp's, while a a dang fine burger, is in a different class from Sobelman's, and I presume any other burger you'd rank higher.
So, barring those two, what do you reccomend? Mazo's? Are they still in business?
