Where is the Tradition of Thai food served on a KhanToke tray?

The Khan Toke tray is associated with the dinner name, a centuries-old tradition; expect to be sitting down to a well-presented dinner on a round tray placed on a table only about a foot or two off the ground. Khan toke dinner consists of rice, Northern Thai dishes, and finger food. While you may be given a fork and spoon, it is encouraged to use your fingers.
