If you'd really like a punch in the face [metaphorically of course] might I suggest going and trying "Special 2" at Orochon Ramen in Little Tokyo [Los Angeles]. They tout it as the spiciest bowl or ramen in the united states. I obviously have not tried every hot ramen, but I can say that I wouldn't doubt it. One of the most painful experiences of my life was trying to tackle that bowl, made me literally fear food for 2 days.
