I'd actually give it a 4.5, but service bumps it to a 5. Only small complaint is the bun is a bit thick and dense for the burger.
Very short and simple menu. Burgers, fries, fountain soda, floats and craft beer. That's it. Good selection of local craft beer.
Burger perfect at medium and cooked to order. Fries thin, little crunch and perfectly salted. Staff very friendly and personal.
