Harmarville Primantis is a Great Place.
I often stop at the Primantis in Harmarville. It's near to where I work, and right at the rte28 Harmar exit, so it is easily accessible to anyone near 28.
The personal pizzas are 12" and include 3 toppings. An excellent after work munch. You can't argue with the 3.85 price for 23 oz draft beers.
Of course the traditional Primanti's sandwich (aka: sammich) is always an option and this location is an easy stop if you have out of town guests.
There are multiple wide-screen TVs with sporting events all around. You can always ask if there is a game on that you don't see on one of the screens.
I've been to many of the city locations, and they are fun, if you don't mind parking some distance away, walking and then standing in line, but if you want to stop, park and go right in, the Harmarville location is great.
