Cat Cafe
It all began in 2004, when the first cat cafe opened its doors in Osaka. Since then, the petting zoo/coffee house hybrids have invaded Tokyo, and business is booming. After removing your shoes and washing your hands, you can relax or play with the cats and kittens while you have your drink. Prices are reasonable, and the rules are simple: no flash photos, no grabbing tails or waking sleeping kitties.
