There's a reason why this cosy little joint in Causeway Bay has been recommended in the Michelin Guide for four years in a row, and its tsukemen is definitely a major factor. The broth is crazy good – a brackish, bisque-like concoction that's rich without being overwhelming – so you don't need to ask us twice to drink up every last drop. And if you're feeling brave, go for the spicy option. It'll have you drooling and sweating for all the right reasons.
