Recommended bowl: Oil injection

This place doesn't look special from the outside, just a regular-looking ramen shop. Ticket machine by the entrance, seven counter seats, one master in the kitchen. The bowls are shoyu-based with a clear soup. Thin, straight noodles and standard toppings. One less predictable detail: On the side of your bowl, you get an injector filled with niboshi oil. Slurp a bit, then pump some oil into your soup and mix it up. Slurp. Repeat.
