Solo traveler, staying in midtown east, somewhat budget conscious
I eat everything and am staying at the waldorf (work thing). Have only a few days. Theatre tix near Chelsea Park. Where to eat before the play? Where to eat near-ish hotel? Any good food near the High Line Park where I will be comfortable eating solo? Lunch on the weekend somewhere in Eatily? Good destination for lunch, walkable from Brooklyn Bridge? Love most asian food, mexican. Thanks for tips.
NYC is very, very solo diner friendly. You're in a tougher neighborhood for inexpensive eats though, especially Mexican and Chinese. Grand Sichuan (2nd/55th) and Pampano (but it might be too pricey) come to mind.
Cheap eats nearby the Waldorf Astoria:
Before your play, I'd recommend Txikito, El Quinto Pino, Grand Sichuan, or Co aka Company. If you are going to see Sleep No More, try for a light meal beforehand!
Near the High Line there are tons of options (including the ones by Chelsea Park I mentioned above). Most are clustered around 14-16th St and 23rd St:
For Eataly on the weekend, be aware that it can be very crowded. Only Birreria and Manzo take reservations, the others don't. Both will definitely take a reservation for 1, though.
Near the Brooklyn Bridge on the Manhattan side, walk to Chinatown!
