Suoh samples the new menu at arch-rival Chinese restaurant Ruklyon. He turns in surprise as Nokoru asks how the food is--is this dim sum flavored with curry?

This is from episode 15, "Once Upon a Time in China", of course. It was fun to see Nokoru and Suoh on opposite sides (yeah, how long did you think that would last?) and was a great excuse for the creators to dress everyone up in Chinese clothing and have outrageous numbers of Clamp character cameos. :-)
