Huge bookshop
Includes a mediocre foreign languages section mostly old classic novels and dictionaries. The management seems to tolerate the thousands of non-customers, using it as a reading room. It is well worth a visit - Borders could learn a thing or two!
Quancheng Square or Spring City Square (the main square)
At night you can watch kids compete in in-line skating, kung fu, or other competitions. Lots of people hang out there so prepeare to be stared at, as Jinan residents do not often see foreigners. If you are not comfortable to be the center of attention maybe it is best to avoid this spot.
Spring City (Quancheng) Park (formerly Jinan Botanical Gardens)
Spring City Park was formerly called the Botanical Gardens. It's quite shady, with a lake and lots of places to sit and relax or have a picnic, so it's a very good place to visit during the hot Jinan summer. It also has a small amusement park at the west end.
The campuses of Shandong University, Shandong Medical University, and Shandong Normal University
Leafy, serene, and pleasant to stroll, especially the Medical University. Avoid the weekends.
Karaoke
One of the most popular activities among the young Chinese. Dong Fang Zhi Yun used to be called Top Party on Wen Hua Xi Lu Culture West Street is a big karaoke bar which includes a pretty decent buffet. Large rooms can accommodate up to 30 people.
New Century Movies (Xin Shi Ji)
Tea Houses and Cafes

If you are after traditioal Chinese tea houses, there are some more traditional looking ones scattered around. They are more popular among business people for the quietness. Tea can be served in traditional Chinese ritual.
