We haven’t really explored much from the middle of Central Park and up. My partner’s friends live in East Harlem, which according to Google maps, begins East 96th and goes north. They chose this neighborhood Thai restaurant, Chu Ros Thai, that they adore and highly recommend. We basically took the local 6 train northbound from the N/W junction, which took about 20 minutes to go up. For a party of 4, we were able to walk in without reservations at around 4 PM on a Saturday evening.
