Originally a playhouse built in the 1890s, like many San Fran buildings Ruby Skye combines the classic elegance of its original Art Nouveau architecture with a decidedly futuristic flourish. Located in the heart of downtown, its two levels house four rooms, several VIP areas and has played host to acts likes Sneak, Steve Lawler and BT live.

“With a high ceiling and a perfect set-up, Ruby Syke is perfectly designed with an elegant style of architecture that you rarely find in clubs,” says Ilan from The Flash Brothers.
