No, this is not poutine. But it could be its cousin. French fries are in the sandwich, not beside it!
It's a tradition in the Pittsburgh area, originating at Primanti Bros., back in the 1930's. My cousin, Sue, took me to one of their suburban locations. I chose the Pitts-Burger which is a beef patty, fries, cole slaw, tomatoes and provolone cheese on soft, fresh Italian bread. Like poutine, I'm not sure I'd order it again, but I am glad I tried it.
On the other hand, I would definitely go back to Lidia's Pittsburgh, located in the Strip District. The food is classic Italian -- Northeastern Italy --- with Slavic influences --- simple and straightforward. Not fussy.
There were 7 of us and we were treated well. It's not stuffy at all; everyone enjoyed their choices; and the service was welcoming. I got to say "hello" to Lidia. She was in town for a PBS fundraiser.Good bread makes a difference.
And here's the restaurant website, which includes more photos and menus.
