Somen are very thin wheat flower noodles, served cold, and dipped in a special sauce. The noodles can be served as Nagashi Somen, which involves letting them flow down a chute of water, often using bamboo. A great example of a family enjoying these noodles can be found here. The dish is apparently quite popular in the summer, as the cold noodles can be quite refreshing.
