Prawn Katsu with Slaw and Chilli Mayo Bao

Never discount the hidden food treasures inside Japan’s train stations and airports. There are gems to be found: Michelin-starred restaurants, izakayas and stellar ramen joints. I discovered katsu burgers before catching a flight and was soon salivating over the crisp, panko-coated prawn patties tucked in a bun with chilli mayo and crunchy cabbage. Why not take it a step further with a soft bao?
