I have tried a lot of Pizza all over, and I swear that Mario's (Chappaqua) slice of regular is the best. The crust is thin, crisp, like airy pastry- not too much sauce, good amount of cheese, well seasoned. Perfect. I had it three times in the last two weeks.
Any other beloved westchester slices?
BTW, I live in NYC now, and nothing compares to what you can find in Westchester, this goes for the Delis, too.
