Recommended bowl: Sapporo black

When it comes to late-night ramen spots in the Susukino area, some might recommend hitting one of the famous miso spots, but many locals prefer this place — Isono Kazuo, open every night from 10pm to 6am. Hidden inside a building off the main street, the shop is small with just seven counter seats. The recommended bowl is the Sapporo Black, a dark, almost dirty-looking soup made from chicken, pork and konbu. The Hinode Seimen noodles come thick and curly. The tare is a black shoyu. All of the ingredients are flash-fried in a wok before being served. The bowl packs a wicked flavor punch, perfect for soaking up the alcohol.
