Ichiran Nishi-Shinjuku is a ramen shop in Nishi-Shinjuku, Tokyo, that serves ramen made with a chicken and beef base instead of pork. Customers choose the spice level, oil amount, broth richness, and noodle firmness, and can add chashu and a soft-boiled egg. When a line forms, staff guide the queue and waiting positions at the front, and the wait is shorter than at other branches. Seats are divided into individual compartments like a study room, which makes conversation difficult.
