Akanoren

Akanoren was the first Hakata-style ramen shop to arrive in the Kanto region, making its debut way back in 1946. Its standard ramen (¥700) comes with thin, flat noodles swimming in a tonkotsu (pork bone) soup enriched with soy sauce, managing to be light but deep at the same time. (Tip: soak up any leftovers with a ¥150 kaedama noodle refill, just like they do in Fukuoka.) Open till 5am and just a quick stumble from Nishi-Azabu crossing, it's ideally positioned to snare hungry revellers as they head home from a night out in Roppongi.
