EZ5 bar-lounge is best around happy hour, like many other San Francisco bars, when a weird mix of Chinese hipsters, business geeks, and loungey types mingle side by side. The décor is part nightclub, part boudoir, and part retro Chinese love den, with a dash of 12-year-old-girl bedroom thrown in for good measure. The walls are orange. The bar is reflex blue. The cushions are pink, red, and orange. And it’s all topped with a disco ball. DJs mix whatever they please, starting at 6pm nightly. There’s even a selection of free fried bar food-which may seem like a good idea after a few strong drinks.
