Stirred together it became sticky and gooey and the natto was delicious, unlike the one I tried in Singapore and made me think it inedible. The bonito flakes and seaweed added flavour and the soba was the star, just cooked and gritty in texture with bite. You know it's good when you hold the bowl to your lips to slurp up every last drop and your neighbour does the same :) the perfect dish to end off my second solo trip.
