Ichiran also distinguishes itself by letting the customers customise the ramen to their liking via a paper form.
There is no change in price no matter the options selected, except for getting over one clove of garlic and over a certain threshold of spice.
The branches serve their ramen using a chicken-based broth and dashi that does not use alcohol-based soy sauce or mirin.
