There are plenty of delicious udon places in Japan, but which is the best? How do you know whether you're eating the finest bowl out there, or being fobbed off with second or third-rate noodles? The U-1 Grand Prix, held in Yoyogi Park, is a championship to determine Japan's best udon. Stores from across the country will gather for the two-day fest to prove their worth, including representatives from as far afield as Akita, Fukuoka and the Goto Islands off the coast of Nagasaki. Go along and lend your taste buds to the cause.
