Directions: Downstairs in the back of the bookstore to the right are single-stall gendered bathrooms. There are additional bathrooms on the second floor: gendered stalls, and one (often immaculate, seldom used) gender neutral single stall all the way in the back, past both other bathrooms.
Comments: They are pretty good about letting non-customers use their bathroom, but please consider supporting your local independent bookstore! :)
