Pretty sure this place would be a 4-5 star review but suprised to see 3.5 stars as of 11.7.11.
The burgers are super tasty and you can put unlimited toppings including grilled onions, mushrooms, peppers, and the usual fixings.
Maybe it's because the burger gets really messy but I don't mind that. I like to put A1 sauce on mine.
If you're going in a group I would order a regular fries to share for 2-3 people. No joke - they fill up a big cup and the bag with fries. Do not make the mistake of ordering 1 order of fries per person.
Everyone talks about the free penuts - it's a nifty addition.
Seriously, overall the value and quality of the burgers are good. I am a huge fan and frequent here since it's close to my work.
