The upstairs is an unassuming, artsy type bookstore. Stroll down the stairs to the basement level and there's a full on porn shop. It's small, but well stocked with DVDs, magazines and toys.
There's a small arcade at the back of the store with a handful of booths. I didn't see any gloryholes but that doesn't mean there aren't any. The presence of an attendant doesn't lend itself to cruising or playing with yourself, or anyone else for that matter, so I moved on. I did note that the booths have doors for privacy, so you could get in a quick wank if you wanted to, but the layout isn't ideal.
Continue through the door at the back of the arcade and you'll find a subterranean entrance to the Soho Cinema, a full on porn theater. The main entrance to the theater is above ground, around the corner from this shop, through a storefront on Walkers Court. Both entrances lead to the same theater. You can pay to enter at either location. See my review of Soho Cinemas for details.
