Weird place, but it is a real "Road Food" place, as noted in Jan and Michael Stern's blog/site/book.
One counter is for hotdogs, another for sandwiches and fries and still another for pizza, and then you go upstairs to eat.
Clearly a place that caters to the still-drunk crowd after midnight from Pitt and CMU.
The fries are just stupid-big. A large could literally feed a group of 10 more. Get a small and go from there. The large is literally an entire bin from the frier. Our group ate maybe 1/8 and tossed the rest.
The dogs are good, though not in the Grays Papaya category.
A definite real road food place/experience when you go to Pittsburgh.
