There is really nothing impressive about the layout or the wall books. Yes, everything is grossly overpriced, but I was far more concerned about the multitude of buckets placed around the store in order to catch water from the leaking roof of the building (this was circa 2015). Also, the staff didn't impress me as being very knowledgeable. For example, I asked about EC comics and the guy at the desk was honestly clueless about my question!
I did, however, thoroughly enjoy browsing his wares. Looking through the store was a joy, but I'd never make a serious purchase there. Everything, as mentioned, is grossly overpriced.
I have no idea how they stay in business and I jokingly wonder, without any proof of course, if the whole operation isn't a cover for a money laundering scheme.
