We come up the staircase from 30th Street on 10th Avenue, down the railway until the end is Whitney Art Museum. It's comfortable and crowded. We walk back from Whitney Art Museum. On 15th Street on 9th Avenue, we see Google's building. There's the famous Chelsea Market opposite. Eat, eat and stroll. Walk around like this, eat, drink and eat for half a day. Think of Xiamen Railway Park
