Another representative Pyongyang dish, ''Taedonggang sungeoguk'', translates as "flathead grey mullet soup from the Taedong River". The soup features flathead grey mullet (abundant in the Taedong River) along with black peppercorns and salt. Traditionally, it has been served to guests visiting Pyongyang. Therefore, there is a common saying, "How good was the trout soup?", which is used to greet people returning from Pyongyang. Another local specialty, ''Pyongyang onban'' (literally "warm rice of Pyongyang") comprises freshly cooked rice topped with sliced mushrooms, chicken, and a couple of ''bindaetteok'' (pancakes made from ground mung beans and vegetables).
