691 Bloor St. W., Toronto, Canada
This place is hardly a secret, but if you've never been there, you're in for a real treat. This is the best soon du bu in Toronto, probably the best that I've had outside of Korea. And it's cheap! Something like $8.
Look, don't come here if you don't like soft tofu stew. The hotter the better. There are only a handful of things on the menu. There'a dolsot bibimbap, but I've never had it.
You can bring Korean food neophytes here, just warn them first. And they should like hot food, and not be freaked out when someone cracks a raw egg over their bubbling stew!
