I don't know if you know but this Sunday is celebrated Brazilian Day in NYC. I cannot go because I'll be working. But on Saturday (September 1) will have a party called 'Lavagem' (Dry), is a Brazilian party with plenty of music and typical food.
The party is free and takes place on the street (Times Square and 46th St.).
Start at 11 am
Those interested will be super welcome!
