Albeit the mindblowingly long wait (40 mins?) for this, I found myself really enjoying the subtle flavours of this udon. The clear soup has a shio-like flavour, and gets lifted by a touch of bright yuzu. The smoked duck is a wonderful topping to offer something savoury amidst the light broth. Meanwhile the smooth and taut udon satisfies in its own rights. I do hope as they get into the groove of busy lunch periods, service time will pick up.
