Kowloon Walled City, Kawasaki Warehouse
This is the most creepy Game Center you will ever visit! In this huge amusement complex you’ll find Arcade Games, Retro Arcade Games, Billiard, Darts, Manga / Internet Cafe and more. The ground floor and the game center are themed. Especially the guys toilets are worth visiting! The girls toilets on the other hand are disappointingly normal. The entire complex is big enough to keep you busy most of the day. It’s located pretty close to the Kawasaki shopping center, which provides all the ingredients for a nice day trip.
