Temporary cafes are popular in Japan. An artist or clothing designer will open up a cafe for a few days to promote something new, whether it be a new album, clothing line, etc. You can go there and buy their new products and get some yummy themed food too. 8Tokyo has a lovely post about the Paul & Joe Sister temporary cafe in Tokyo where this gorgeous food was served. They have really cute cat-themed merchandise too. Check out the full post here.
