Being cheesy is a good thing at this shop. Alleva Dairy, which bills itself as America’s oldest cheese shop and was founded in 1892, is here for all your savory cravings. Stop by for fresh mozzarella and other cheeses at this store that also turns out hearty hero sandwiches, stuffed peppers and salty meats like prosciutto. As an added bonus, you might run into actor Tony Danza, who became a part-owner of Alleva a few years back. Alleva’s stand at the feast will be in front of the store at 188 Grand St.
