Authentic, perhaps not, yummy?- you bet!
Famous Dave's is a little hokey, a little fakey, but still...the Dave's Ultimate Burger with bacon and chopped pork on top of an enormous burger is literally to die for! My personal fave is the Georgia chopped pork- as a platter it's a whole pile of food for ten bucks. the Mr. really loves the bread pudding on the rare occasion we order dessert!
