Northerners serve their meals on a raised vessel called "tok." Parties and functions are called "khan tok": tok dinners. There are various kinds of food on a tok, which come in three different sizes: "khan tok luang" (large tok) is used in northern royal palaces and principal temples; "khan tok ham" (medium-sized tok) is used by large families, and "khan tok noi" (small tok) by small families. Lannastyle khan tok parties have become a very popular tour program that educates tourists about one of the most enjoyable cultural features of the North.
