Time Out says

A stylish LGBT crowd flocks to this classy roving club night.

Without doubt Switzerland’s LGBT capital, Zurich has its very own stable of slick, sexy, large-scale circuit parties, each of which touches down every couple of months at some or other major venue. And for all their go-go boys’ cartoon muscles and micropants, the formulaic offerings dished up by the likes of We Party, Angels and Aviator could mostly be anywhere in the world. Jack on the other hand brings way more character and class to the table, while still magnetising the city’s dishiest queer clubbers. New York’s Larry Tee, Spanish super-selekta Borja Pena, Germany’s Gloria Viagra and the cuddly compadres of London’s Horse Meat Disco are among regulars behind the decks, while the stylish crowd adds an urbane hipster edge to proceedings. Take the next day off, be ready to dance as well as flirt, and set facial hair to stun.
