Fairly spacious by cat-cafe standards, Keurig provides ample table and counter space for visitors and a stimulating environment for the resident cats, with lots of climbing and perching opportunities. There's a good supply of cat toys as well, and the staff seem to be proactive in keeping the cats entertained. There were around 30 cats when we visited, including many lively kittens.

The cafe menu is one of the biggest we've seen in a cat cafe, with numerous fancy desserts and beverages. The first drink is included with the price of admission. Cat treats are Y100 and come in a small plastic capsule which doubles as a cat toy. The treats aren't just kibble, but a bonito-flavored fish paste which seems to be quite popular.

The admission price is Y1000 for one hour, which includes one drink.
