This shop has a vibe more like a garage sale than a real business. Shady part of town, shady shopping area and shady owner.
The store is a mess and you would have to be either the owner or an idiot savant to find anything. Quality of back issues is poor. Most are of very poor condition.
You strangely get the feeling that you might get mugged while in this store.
Edit: I apparently visited the previous location. So in all fairness, I will visit the new spot.
