Kamo hiya-atsu — Sanuki udon (chilled noodles, hot broth with duck). Onsen tamago on the side.
Lunch at Koya Udon, in Frith Street, Soho (London).
Tasty. Very tasty, in fact. And well worth the diversion, if you're anywhere near north Soho.
Update: This was just a quick light satisfying lunch. Next time I intend to linger, to try out some of the creative side dishes prepared by chef Junya Yamasaki.
