Shhhhh. Do not tell anybody about this place. This is definitely one of the hidden gems on the North Shore. Piero's has some of the best thin and pan pizza in Chicago. The Ascolana is my favorite. The funny thing is I keep trying new pizza places and really liking them but I have to tell you that Piero's is the real Italian deal. Right down to mamma that works the register up front. I love her. One time I came to get pizza and she was speaking to the boys in back in Italian and she did not seem happy but she is always lovely to customers.
The pizza is Grade A top of the line fresh ingredients. They put their hearts into the pizza and it shows. You feel like you are picking up pizza from a small villa. About 4 tables and that's it. This is not a sit down type of place. You order or have it delivered, cash only no excuses. Old school register and receipts. That's it, that's all. Love it or leave it. Wish more places were like this on the North Shore. Anyone who is reading my review and orders from Piero's knows what I am talking about.
The great thing about Piero's is that they will never be a sit down pizza place so it will keep our hidden gem quiet from  everyone else. Too many places that start out small end up getting much bigger because the entire Chicago area finds about them and takes away the little slice of heaven of a restaurant that the suburbs may have.
Anyway try it if you live close. You will not be disappointed.
