Recommended bowl: Kyoto Roots

Open every day until 3am, this Osaka staple has been on the circuit for years. The brand now has three branches, but this Tsuruhashi spot is the flagship. The ramen served here is actually Kyoto-style rather than Osaka-inspired, as the master trained at the wildly famous Kyoto ramen institution Daichi Asahi Takabashi. Featuring a light, pork-based soup, made with chicken and a soulful shoyu tare, the bowls are loaded up with thin slices of chashu and negi. Fried rice and gyoza available on the side. Go get it.
