Jjanjjan Huoguo Jeonpo Branch in Busan lets diners choose from red broth, white broth, anchovy broth, or a half-and-half combination, along with beef, lamb, or pork. Vegetables, noodles, and dumpling ingredients circulate on a conveyor, so diners take only what they want. Solo seats are available, and diners do not need to leave their seats except to get water or sauce. The broth is closer to mild and plain than rich in flavor.
