I did another one of those combos today, spending a few hours at The Terminal and venturing out for a quick nearby lunch. This time around I ended up randomly opting for a small udon place – Iroha – in the Harajuku back street area just south of The Terminal. They had an interesting take on Italian/udon crossover dishes, I went with the carbonara udon option and... yummy. Insanely tasty. A new favorite.
Find your way to the KDDI building in Harajuku, and walk past it in the general direction of Omotesando, following the extension of Takeshita Dori. Walk onto the first street appearing to your right and boom, there it is. Bento.com has the details if you need them.
