Going to NYC with someone who's agoraphobic would not be fun, lol. My favorite places to eat in NYC was Arte Cafe on the Upper West Side, if you like Italian (recommend the early bird specials). Also loved Connoly's for Irish food in Midtown.

Funny enough I wrote an article about visiting NYC at Christmas a few months ago: https://medium.com/globetrotters/christmas-in-new-york-city-something-to-experience-once-in-a-lifetime-afadf78faf3c
