If you come to Pittsburgh, you have to make a stop at Primanti Brothers. It has been featured on several travel and food shows like Man Vs. Food.
My friend took me here for dinner and each of us ordered a cheesesteak, which is considered the #2 best seller. This sandwich is HUGE! Mainly because of all the coleslaw and french fries piled high within the sandwich. The cheesesteak itself was okay and the meat looked processed. Not that great. However, the bread is nice and soft. I also ordered a pint of Yuengling on draft. Good beer...
If I do come back, I'm interested in trying the roast beef. It seems like this restaurant is hit or miss depending on what you order. Also the original location is in the Strip district while this location is near the University of Pitt campus, so lots of college students.
