Name of Soon tofu place on Yonge/Finch
I suspect you're thinking of Buk Chang Dong Soon Tofu, which is a branch of the original Korean joint with the same name on Bloor St. W. near Christie. Both restos are deservedly popular with the local Korean citizenry, who enjoy the six or so items on the menu, most of them delicious soup/stews with assorted toppings, and served with four or so delightfully zippy side dishes. In short, lots to eat. Last time I was there - some months ago - just about everything on the menu was $8, taxes included. Little wonder both places are often mobbed.
