With some of the best ramen in the world available in Japan it amazes me how people rave about cheap chain trash like Ichiran. It's like going to the States and saying that you had these amazing burgers at a place called Wendy's and everyone should eat there. Yeah the burgers may be consistent and better than the average Japanese burger, but you're wasting a meal eating there when there are so many better options.
The Michelin guide's list of ramen restaurants certainly won't do you wrong:
