I had the chance to check out Buk Chang Dong Soon Tofu at Yonge south of Finch (the old China Grill location http://www.chowhound.com/topics/350646 ). I've been to their downtown location and was looking forward to this visit. They had been open for a week or so at this new location.
The menu was as expected; four variations on the tofu soup, and some additional staples such as Dolsot Bibimbap and Bulgogi combos. I got the Soon Tofu with dumplings (spicy) - 6.99 if I remember. The place was packed, my two buddies and I were lucky to get a table after a few minutes. The food took a long time to arrive, but service was very good and attentive, and they gave us lots of appetizers (two types of kimchi, seaweed, and marinated soybeans) and came by to check on us regularly.
Once the soup arrived, we weren't disappointed. Piping hot, with the signature (red bean?) rice in a stone bowl on the side. Crack the raw egg into the soup and you're good to go! It was not overly spicy, just perfect with the added rice. Actually it was more like a stew than a soup. There were two large flat dumplings. The tofu was the soft and smooth type, and the taste was excellent. Looks like they built up the flavors properly, starting with a good stock. However, I suspect there was some MSG added also, from the tell-tale dry mouth and thirst after the meal. My friend's Bibimbap looked good too (you'd be hard pressed to mess up a Bibimbap, as long as the bowl is hot enough).
MSG notwithstanding, I'd recommend the place. When they settle down a bit, I'm sure the service will speed up, and I'll be back. Especially when the weather gets really cold.
