Have you ever had Uzbek food? Me neither until I went to Nargis Cafe. It's kinda like middle eastern food mixed with Ukranian food. It's so good and so inexpensive.
My second-favorite outdoor-place in Manhattan. The abandoned 1.6 km rail tracks running above Chelsea down to the Meatpacking district were turned into an above-ground park. Perfectly nice place for sitting in the sun, reading, relaxing, having lunch in some green spot in the city. Nice views at the Hudson River, New Jersey, the Statue of Liberty (little small from there but still visible) and the architecture around Chelsea.
The Christmas light House in the Bronx is a neighborhood fixture that is hard to miss. It is decorated year round with life size statues and is painted bright pink. Though it draws most of its audience during the holidays it is an anomaly throughout the seasons. Such a bizarre place with such exuberant colors and vibrancy attracts an artists eye and will draw you in.
