The place is quite small and they don't do bookings, a bit of queueing is usually required. It is well worth it though, probably the best udon i've ever had.
Let's now look at some food..
Curry atsu-atsu (warm udon in hot broth) with some misc vegetables. A must have
Ten mori - battered prawn and veg. Another must have
Gyu-katsu. Beef katsu essentially, medium rare. DIVINE
The whole lot.
Credits to Soi for the recommendation!
