In the pantheon of great Park Slope sandwiches, the offerings at the neighborhood's only butcher shop (for now) can't be overlooked. From homemade roast beef to piping hot chicken and eggplant parm, there's no other Italian deli making sandwiches like these in the area (again, for now).
Aside from top-notch pork, beef, and homemade sausage, the claim to fame of M&S Prime Meats, on Fifth Avenue between Second and Third Streets, is its fresh mozzarella. It's a major player in my personal favorite sandwich of theirs, which combines house-smoked homemade fresh mozzarella, prosciutto, fresh basil, and a drizzle of balsamic vinegar. On a semolina hero topped with a sprinkling of sesame seeds, it doesn't get much better than this.
