DJs JJ Lanz and Roberto X help Nathan Kelly and City Alliance Productions move their Union Square-adjacent party from Thursdays to Sundays. Things will start a bit earlier as well—but they’ll still have the usual rooftop hookah and go-go boys and will sling free drinks from 6:30pm–7pm and 9:30pm–10pm. 6pm–1am; free.
