Songa is a Korean restaurant in Tokyo that serves gamjatang (pork bone and potato stew). The ugeoji gamjatang and red gamjatang can be ordered with toppings such as ugeoji and dried spinach, and the meal can be finished with bokkeum bap. Walking in without a reservation can mean a long wait, and both lunch and dinner take cash only. The meat has many bones, and the broth and potato flavors come through separately.
