Nikomi no Takara
Founded in 1964, this is Osu's only specialist in miso-nikomi udon — firm house-made noodles simmered in a clay pot with a secret blend built on Hatcho miso, rich-looking yet mellow. Breaking the soft-set egg into the broth is the moment regulars live for. A bowl that has anchored the Osu arcade's food culture for half a century.
Reviews praise the rich-yet-clean miso and properly firm noodles. Lunchtime queues are common but turnover is quick.
