On the first floor, a Reserve bar, baristas prepare coffee and serve affogato and amaretto affogato. The first floor is the Reserve store and the second floor is a regular store, and by around 1 p.m. it is crowded enough that the large tables for opening a laptop are already full. The restroom is outside the store, so you have to walk a distance.
