At Sora no Iro ソラノイロ ramen shop. Found at B1, Ramen Street of Tokyo Station.
No meat, all-vegan friendly, ビーガン. The taste is quite unique as there’s no trace of meat in it. They’ve got non-vegan ramen as well, for carnivorous beings. (^∇^)
You can ask the staff to help you find the right button for the vegan ramen on their vending machine. (≧∇≦)b
