Salvatore's is a very popular spot to grab some chicken, pizza, or a variety of other things. They have been recognized as having some of the best wings around. Their pizzas are good too. If you want a HUGE pizza...come on over here. They make one that is over two feet in diameter if I remember right. We had to put it in the back of my co-workers truck when we brought it back to work.
If you are looking for an asian grocery store, this is about as good as it is going to get in Pittsburgh unless you go down to the Strip which is downtown. This is closer to the Monroeville side (east of downtown). So if you need noodles, vegetables, or anything else from a store like this, you should check this place out.
What to pay: standard prices
This is actually a hidden gem of Wilkinsburg. This pet shop has some very interesting and different animals available for purchase. Like I said in my title...piranha and caymans have been sold here, as well as a lot of unusual fish. It's worth it just as much to check out even if you are not going to buy anything.
What to buy: a new pet of course...or pet supplies
What to pay: standard pet store prices
