Park Slope, Brooklyn.
I was in the Landmark Pub just once, in 1996. It looked like the house of an old woman with serious pack-rat tendencies, which I believe it actually was. The front room was almost entirely full of old bed frames, lamps, ugly paintings, broken toys, etc. There were small pathways between the stacks of junk. In one corner a guy was playing guitar and singing, while bar patrons accompanied him on plastic toy instruments. The old lady puttered around serving bottles of Bud. I don't think any of this was entirely legal, which may be why the place has been closed for several years. Also the old woman was very old. Also the whole thing was much too weird for 7th Avenue.
