Peppi's is delicious. I ordered the #7 (RoethlisBurger) which is blend of hamburger and sausage with american cheese and egg. It was fantastic.
This is exactly the type of sandwich I have been looking for in Pittsburgh... unabashedly unhealthy and irrefutably delicious. It reminds me of a somewhat better version of my favorite sandwich chain from Detroit, Tubby's. In fact, I intend to give Tubby's bottled dressing a whirl on my next order from Peppi's.
