The different views of the skyline are unbelievable. I especially like rooftop views from different apartment buildings. Try to get on top of an apartment building. This is the view from my apartment...
This is one of my favorite bars in Manhattan. It has a courtyard in the middle and they only serve a large selection of Belgian beer. It's always dark with red lights so it's like a giant darkroom with everyone developing hangovers instead of film. The courtyard creates a front bar that is open on the weekends, so if you get cornered talking about architecture you can escape over to the front bar and watch people walk down 4th street.
