RE: Sheetz Chili Dogs
I agree with spinal tap - the dog are OK. but, you're better off getting subs, bagel sandwhiches and the like. Also, I have found that the heated sandwhiches, melts etc. tend to become very soggy, which has a lot to do with the fact that the sandwich is still steaming (releasing moisture) when wrapped. So, when we stop at sheetz, it's either cold subs or toasted bagel, but nothing grilled or otherwise warmed.
I recently (post New Year's Day on return trip from Buffalo to DC) had their fries, which I also enjoyed. We have 7-11s all over the place, and when I visit my buddy in Philly, we always hit Wawa's (because he's a Wawa man) But, as spinaltap said, Sheetz is leading leading the way, and IMO 7-11 and Wawa's has a LOT of catching up to do.
