I've been in Pittsburgh for 3 days and I have eaten primanti brothers everyday. I'm about to go again now for breakfast. When people tell you you have to eat here when you come to Pittsburgh they are CORRECT.
Only complaint I have was the "pittsburger" sandwich... that hamburger patty is not good. It's pretty gross. I don't know how it's a best seller. Acquired taste maybe. BUT the roast beef, hot sausage, kielbasa.... TO DIE FOR.
