This used to be an old standard when I worked in the area, but I still made it down once in a while after I left that job. Great wings and good pizzas too. They also sell the largest pizza I have ever seen. It's 30 inches! Bring your truck if you want to take it home.
This place is so successful that they have changed their decor numerous times over the years (gets better and better).
I can't really think of any reason why you would want to venture into Wilkinsburg, but if you are, this can be a place to eat.
