Osaka (大阪市) has traditionally been referred to as the "nation's kitchen" (天下の台所 tenka no daidokoro), or the mecca of gourmet food, as supported by the saying "Dress (in kimonos) 'til you drop in Kyoto, eat 'til you drop in Osaka" (京の着倒れ、大阪の食い倒れ).

Regional cuisine includes okonomiyaki (pan-fried batter cake), takoyaki(octopus dumplings), udon (a noodle dish), as well as the traditional battera (バッテラ) sushi.
