Recommended bowl: Blue ramen!

Master Koizumi-san is a different kind of ramen chef. Not only does he frequently sport unique, neon-colored hair styles, but he serves up a bright blue ramen that is unlike anything you have ever seen. The main menu item is a chicken-based paitan ramen, but many customers gravitate towards the electric blue soup (also chicken-based) of Koizumi-san's 'blue' ramen. Topped with chicken oil and tori chashu, noodles supplied by Kanejin. The secret ingredient that creates the color? All-natural spirulina algae.
