At first we thought we were seeing things, that maybe this had been there a long time and we just hadn’t realized. Then we seemed to remember that the bodega that had occupied this corner seemed to have had a going out of business sale in October or November. So, here, friends, is the latest addition to the Fourth Avenue retail scene: Slope Natural Plus. It’s at the corner of Fourth Ave & St. Mark’s. Yes, it isn’t much, and it’s probably a really overpriced place replacing something affordable, but remember we’re talking about Fourth Avenue and every opening is like watching Him walk on water.
