Before there was 5 GUYS there was
HERFY'S and before there was Herfy's there was BOB'S BIG BOY. OMG it's good.
The first time I tried a Herfy's burger I wondered why it tasted so good, then I realized it reminded me of Bob's Big Boy. This means the special sauce is more SPECIAL and a lot less MAYO. The fries are huge so you'll only need one to share but if you want to go large, go big and get an order of onion rings too.
CAUTION: Shakes are great and readily available, so limit your Herfy's visits to once per month.
