The "O" or, affectionately and perhaps accurately, the "Dirty O" is Pittsburgh hot dog tradition. It's a big menu, but the thing to get is their hot dog or a chili dog. And fries. Fresh cut fries, fried twice. Great fries. That's a small portion above, a mountain of fries that even I couldn't finish. Order your dogs and drinks up front, the fries at the rear counter.
