I love this excellent independent arthouse theater in the Lower East side. Metrograph projects archive quality 35mm and independent films. Tastefully decorated, there is also a candy store, bookstore and restaurant.
The best way to enjoy Manhattan is from Brooklyn. Transmitter Park offers views without the crowds, and you can pick up coffee-to-go and treats from nearby Ovenly. The India St/Greenpoint Ferry is a 5 minute walk and will take you all the way to the Rockaways in the Summertime.
