I was in Pittsburgh for a day and had to stop by Primanti Bros since it was on every "places to visit in Pittsburgh" list that I saw. The chain restaurant is known for the hearty sandwiches stuffed with fries and coleslaw. I ordered a Pitts-burger (one of their many sandwiches stuffed with fries and coleslaw) and I was not disappointed by all the hype around the restaurant.
Note to non-Pitttsburgh natives: the menu at Primanti Bros claims that the Pitts-burger is the #2 best seller. This is an inside joke regarding Iron City Beer being the #1 seller. (So don't get confused like I did and search the menu for a ridiculous amount of time looking for the #1 best seller that did not exist.)
The service at the restaurant was great but a little slow.
