Salvatore's is hands down the best pizza in/around the Madison area! The ingredients are always fresh and usually sourced locally and their appetizers and small plates are also very tasty. I really enjoy how they mix different toppings to get optimal flavor in every bite.
I also like the quaint, smaller atmosphere of their restaurant. If you haven't heard of Sal's there is a good chance you might drive right by it.
I have yet to try their new downtown location but I can imagine it is just as good as their original SP location. I have told many many people about Salvatore's and anyone who has tried them has been just as impressed. Highly Recommend!!
