Mattari Pudding Dotonbori is a cafe in Dotonbori, Osaka, that sells custard pudding. The pudding has a rich flavor reminiscent of egg yolk and cheese rather than milk, with a texture that melts smoothly in the mouth. You can eat it right in front of the small shop, and when you finish, you hand the empty container back to the shop and they throw it away for you. The shop is small and not very noticeable, so it is easy to walk past while strolling through Dotonbori.
