I come to Hug Ga Ne whenever I visit Toronto. They open 24 hours! Their Sun dae guk (Korean soup made of pork blood and noodle sausages) makes me think of my hometown. It is a food I would love to eat after flying for hours. Very mild comfy food, but if you add hot paste, it is also excellent.
They also serve Korean BBQ, which is great. But I found their ventilation is not good enough for Korean BBQ. Many people make table BBQ in evenings, so I prefer to go in the morning to eat Sun dae guk.
