Second branch of the Hakata ramen restaurant on Regent Street. The Soho spot has a more restaurant-y feel than the canteen-like original. There's the same range of noodles in long-simmered bone broth, plus steamed hirata buns stuffed with juicy pork slices, chilli sauce and mayo.
There is also a saké sommelier Mimi Tokumine, who is often on hand to offer advice to diners. However be warned this is not a bar; arrive on your own and you'll not be seated until the rest of your party arrives, and you need to order a meal to go with your drinks.
