If you haven't been there yet, you have to go. Mad Mike's is one of my new favorite burger places. It's up there with Terry's and City View Tavern good.
The best way to describe it is to think of a bigger and fresher Five Guys burger. It is plenty of food and definitely plenty of fries but the burger is so much juicier and more flavorful than Five Guys.
It is located in Florence and it is worth a trip down!
I've been there a couple times now and both burgers were awesome. Take a look at the pictures.
