Ok, its a chain. They have them everywhere. However, if you are not a people person, then this is the best thing on earth. Private small "booths" where you don't even have to look at the person next to you OR the person who serves you. AMEN!!!
This isn't the best ramen you'll have in Japan, but it's a decent option if you are wandering around and can't find anything else and are shitfaced. The paper you fill out gives various options for how soft/hard you want your noodles, how mild/spicy your broth should be, how fatty/thin, etc. I always go for hard noodles, fatty, and pretty spicy. That makes a decent bowl of Ramen considering its a chain. This is by no means close to the top 100 ramens in Japan, but its the best choice between McDonalds and Ichiran at 4am.
The quest to find a decent bowl of ramen in every country on earth.
