Webster Hall is a solid venue, and a frequent stop for many great bands on their rise to glory. If you've only got a few nights in the city, chances are a great act will be playing here.
I discovered the Frick my first week in New York, during a heat wave in August. The galleries were surprisingly empty, with only the occasional visitor strolling through the rooms, gently creaking the floorboards. I stood for a while in front of the Bronzino, a portrait of a boy standing against a background of green drapery, and then sat in the courtyard for a long, cool hour.
I love sneaking over here in the middle of the day to see a movie - they always have the best selection of films. I recently saw Pina in 3D and The Kid with a Bike here, and another time I saw Bela Fleck play the banjo after a screening of Throw Down Your Heart.
A great way to escape the city...Especially amazing in Spring when the cherry blossoms are out. I love the Japanese pond, the famous NYers walk with plates for Arthur Miller or Lee Krasner and of course the green house.
