What is the 'Ramen Jiro' style of ramen?

Ramen Jiro is a famous chain of ramen shops in Japan that is known for its massive portions and its highly customizable ramen. A bowl of Jiro-style ramen is a mountain of noodles, bean sprouts, and cabbage, topped with a thick slice of chashu and a generous amount of garlic. The broth is a rich and fatty tonkotsu-shoyu blend. Jiro is not for the faint of heart, but it's a must-try for any serious ramen lover.
