As a commemorative event, a stamp rally celebrating the 60th anniversary of the opening is currently underway with the cooperation of 7 restaurants in the building. Order a special collaboration menu item at any participating restaurant to receive 1 stamp. Collect all 8 stamps, including the one at the commemorative exhibition corner (unattended, so please stamp it yourself), to receive a stainless steel tumbler (350ml) featuring the building's elevation drawing. With 3 stamps, you will receive a commemorative ballpoint pen. Please note that the tumblers are limited to 100 pieces. We look forward to your early participation. Until 10/22
