Hidden down a small street off of Huashan Lu next to those tennis courts, Time Passage (or Yesterday, Today, Tomorrow in Chinese) has been running since 1994, making it one of the oldest bars in the city. It's a great place for a relaxing drink during the week and every weekend they have live blues, jazz, or rock music. The crowd is a healthy mix of locals and slightly older foreigners looking for a low-key place to enjoy a beer. They also have activities like chess, good playlists, and great conversation with the bartenders.
