Nick Carr of Scouting NY has found the little sister to NYC's narrowest house: the skinniest store! Ever the eagle-eye, Carr spotted the store while walking along Columbus Avenue in the Upper West Side. The "Amazing Store and Smoke Shop" is squashed between two residential buildings, and it is no bigger than the width of the door frame, about three or four feet. Inside, it looks pretty much like an inverted sidewalk newsstand. The space goes back about 12-feet, the walls are lined with magazines and candy, and the cigarettes and cold drinks are behind the counter.
