If you want to drive for a GOOD burger and one far bigger than Thurmans head to Denny's Beer Barrel Pub in Clearfield, PA. I've never been to Thurmans but if it's compared to just "big bar food" then this place has it beat.

Downside is there isn't much else to do in Clearfield. I was only there about 5 years ago b/c I have a buddy that lives there and graduated with the owner of Denny's.
