Korean foods can be largely categorized into groups of "main staple foods" (주식), "subsidiary dishes" (부식), and "dessert" (후식). The main dishes are made from grains such as bap (a bowl of rice), juk (porridge), and guksu (noodles).
Many Korean banchan rely on fermentation for flavor and preservation, resulting in a tangy, salty, and spicy taste. Certain regions are especially associated with some dishes (for example, the city of Jeonju with bibimbap) either as a place of origin or for a famous regional variety. Restaurants will often use these famous names on their signs or menus (i.e. "Suwon galbi").
