Seems this place is closed for now, but back in 2013 we found it our second favorite place in US (after Chikie's & Pete's in Bordentown). Quaker Steak & Lube was located closely to our motel and when we went here, we were just impressed.

The Bottom Line
It would be sad to learn that this place is closed (in 2015), it was a great place, with great food (Best Wings in USA), awesome atmosphere and good prices.
