This is the best soon tofu restaurant in Toronto hands down. I've been here many times during lunch and dinner, and it has never disappointed. My favourite is the Pork Soon Tofu (~$9) which comes in a generous portion for the price. Remember to crack the egg in while it's hot! I think they make their tofu in-house, which explains the fresh soy taste. Meatballs are nice and tender, and the broth is very flavourful and balanced. Sometimes I even ask for no spiciness just to enjoy the broth on its own. There's a good variety of side dishes as well, especially tofu ones you won't find at other places.
The staff are quick and friendly, always checking in if you want more side dish refills. Best of all, this place is significantly more spacious and quiet compared to Buk Chang Dong across the street.
