This is a chain of vegan ramen restaurants located in multiple train stations. In all the 3 locations I tried, the food was consistent and yummy They also sell ready-to-eat vegan ramen boxes, perfect for on-the-go dining during your travels!
Cost: ¥ 1,000–2,000 per person.
Note: When you go to the train station to only dine, you still get charged on entry/exit. So you may want to time your travel in a way that you can eat enroute to somewhere to avoid that extra fee.
