Taipei's Breeze Center is built on the site of the old Taipei Hey-song beverage bottling plant. There's a nice little museum in the mall called the Hey-song Pavilion dedicated to the history of the Hey-song company and its' products as part of Taiwan's culture from the Japanese Colonial period, through Kuomintang martial law to today.
The Pavilion takes the form of a 1950-60s Taiwan market street with vintage bottles, marketing tchotckes as well as films and goofy games. A vending machine provides the company's product, though Hey-Song Cola is apparently no longer available. The museum is free, signage is in English and traditional Chinese, and is a nice place to burn half an hour.
