I hate giving this place only three stars. I wanted very badly to LOVE it, but I came to my decision of three based on the pierogies (earning 2 stars) and the barbecued chipped ham (earning 4 stars). Service-wise the owner is extremely friendly (5 stars) but my order took FOREVER (1 star).
When I was little girl, a church in downtown Pittsburgh would have a Polish festival every year, and they would have little old Polish ladies make the pierogies. My dad would always bring home a boatload of them, and WOW were they delicious... thin dough, fat with potato stuffing, and DRIPPING with butter. The pierogies @ Willies looked more like raviolis to me, with very little stuffing and a whole lotta dough. Just not my cup of pierogie tea.
However, they did have bbq chipped ham, which I haven't had since a kid. Most people haven't even heard of chipped ham, but I remember eating it when I was little. I got two orders of the sliders and they really were delicious... super salty, a little sweet and tangy. Just like when I was a kid and my parents didn't know any better.
The guy that runs the place is SUPER nice and we talked Pittsburgh for a while. TONS of Steelers & Pittsburgh memorabilia. He was running the stand on his own that day and he was busy, so it took a LONG time for him to get my order out. Luckily the hot dog stand is housed within a giant antique store, so I was happy to look around until my order was up. But had I just had to stand there and wait, I probably would have turned into one bitchy pregnant girl.
Overall, I'm glad I tried it, but since it's about 20 minutes away from home, I don' think I'll be a frequent customer... but maybe if we're in the neighborhood sometime and I'm craving some barbecued chipped ham.
