Bunn Mike is a tiny place with a short menu to match. You’re here for a banh mi, and you can choose from six variations, ranging from one with grilled pork to a vegan option. They also serve chicory coffee, chips, and sodas. Seating is limited and the space is already tight to start with, but Washington Square Park is only two blocks away. One sandwich will fuel your afternoon, but you could also get away with sharing between two people.
