Everything I have to say about Freddy's has been said in other reviews here, so I'll make it quick and just hit the high points.
First, this place is pretty much a copy of Steak & Shake. The burgers are the thin patty "smashed" style burgers and the fries are thin and crispy matchstick style fries. Both the burgers and fries are very tasty IMO.
When you get sick of the large chain fast food burgers, Freddy's makes a nice change of pace.
