Heyday harks back to the glamorous days of 1920's and 30's Shanghai. It's a small, intimate venue showcasing local jazz talents like Coco Zhao. To go with the music is a list of cocktails that riff on Shanghai's decadent jazz era, with names like Heaven Built on Hell, or Qi-pao. Live music seven days a week, starting around 9pm on weekdays and 9.30pm on weekends.
