tldr: it's the cheeseburger of ramen. big on portions, big on garlic, big on fat, big on salt, heavy, no delicacy or refinement, staff bordering on rude, no patience for newbies or tourists. if you go there, you should go knowing what you want and knowing your limits, and the chef
will chastise you if you ordered too much.
