You’ve got lots of great options here, Steve so I’ll add just five more.
Anticuchos, Antojitos Doña Fela, Jackson Heights, Queens
Street vendor on Roosevelt Ave. near the northwest corner with 90th St., Friday 10am-6pm, Saturday and Sunday 6:30am-6pm (though anticuchos are usually available only from early afternoon)
Guyanese black and white puddings, Ousha’s produce stand, Richmond Hill, Queens
Street vendor on Liberty Ave. near the northeast corner with 114th St.; at last encounter, weekdays (except Wednesday) after 3pm, weekends after 1pm
Mangu con tres golpes, El Nuevo Bohio Restaurant, Morrisania, Bronx
Punjene paprike, stuffed peppers, Cevabdzinica Sarajevo (aka Sarajevo Fast Food), Astoria, Queens
Thiebu djeun (red), Keur Coumba, West 116th Street, Manhattan. This Senegalese restaurant prepares both red and white versions of “cheb” on a rotating basis; both are good.
Should you decide to stay in New York on Friday night and drive back home on Saturday, you might consider a roundabout path via the Verrazzano-Narrows Bridge to Pig Island, at Snug Harbor on Staten Island. I’ve never attended this annual event, but various meat-loving friends tell me good things.
I hope that you’ll prepare and share an itinerary so we can see, ahead of time, just how many places you hope to try on your all-too-brief visit!
