When I was in NY I loved street food as a treat no matter the ethnicity, including the notorious if misnamed "dirty water hotdogs". Same with walk-in shops either uptown or out in Queens that offered ethnic fare to go, empanadas, Cuban sandwiches, Malaysian specialties made by expats from Penang, etc.
And Sixth Avenue in midtown at lunchtime was food cart heaven. Used to grab something from there at least a few times a month and export it to the then newly renovated Bryant Park, sit on the grass, admire the flower gardens, catch a few rays, sometimes in summer there were stand-up comedy shows... it was a lunch hour worth taking away from the standard lentil soup at desk routine, for sure.
Also really fun at work were birthday celebrations for some East Asians on staff. We'd take a four-hour lunch on some Thursday, maybe a dozen of us, take the train down to Chinatown and up into one of those no-name fourth-floor restaurants where there's no menu and no English spoken, you just go with someone who knows the place and they bring out the food... and the food.. and the food...
