第 5 集: 警方介入後，花川尋求更佳的湯頭配方

5

Kurita offers to buy Yamaoka a cheap meal, so he takes her to an alley of vendor's stalls where he selects one run by Hanakawa which serves handmade soba noodles. The noodles are perfect, but Yamaoka states that the broth is lacking in flavour. Police arrive to shut down the stall because Hanakawa has no licence, but after police Inspector Nakamatsu tastes the meal, he offers to provide a licence if the broth improves. Hanakawa tries different recipes but is unsuccessful until Yamaoka tricks him into visiting a soba restaurant where he learns their secret broth recipe. Hanakawa uses it in his stall, and when Inspector Nakamatsu visits again, he grants him a licence, however Nakamatsu still expects some improvement in the flavor of the broth. (Source: Wikipedia)
