Kouryu Ramen Restaurant is located behind the Alta Studio Building in Shinjuku. East Exit of the JR Shinjuku station.
Their ramen soup is pork not chicken based. Outside of the restaurant there is a ticket machine. Insert your money and select your ramen. We normally get the one that you can customise to your own taste and it is only 800 yen.
Don’t forget to press the black button to get your change.
On the sheet they give you, you can select the tenderness of the noodle, with/without green onions, hot sauce, with/without pork, etc. and then you can pick four toppings from 8 selections.
If you don’t read Japanese, no worries. They have a cheat sheet in English.
If you are still hungry, insert a 100 yen coin into the slot. They will get you a second helping of noodles.
