61B Cafe was an impulse stop in my life, and I am still unsure of my overall feelings months later. It is a cute little cafe style store with indoor and outdoor seating. My friend and I ordered a raspberry pastry ($2.50) and Pellegrino sodas. The raspberry pastry was ok but not too special. There were a variety of soda flavors, which was nice.
As others have mentioned, the service is a tad off-putting. It is cash only, and they are definitely rude about it if you don't notice the tiny sign. Still tbd on my feelings. I guess it was just OK, but I don't know that I would come back.
