Five Lamps Tavern, located at 2657 Broadway (between 105th and 106th Streets) is a must visit.  18 mostly quality tap beers and an outdoor space (which is still under construction).  Friendly staff.  A good spot to include on the Upper West Side craft-beer focused NYC bar crawl.  Tasty weekend brunch menu (try the IPA-brined french fries or the breakfast flatbread!).
