I had Korean soon doo boo (sp), soft tofu, at Seoul Garden in K-town recently.
The facility is on the second floor of a building that has a buffet/pastry shop on the ground floor. The soft tofu was appropriate, in texture. A "combination" soon tofu (with kimchi, beef, seafood) was better than the "seafood" soon tofu. Each was a smallish serving appropriate for one person, at $8.95/order ($12.95 with some kalbi included, although in this context the kalbi are not prepared by the diner at the table). This was better than the other soft tofu place I visited within the last several months (I can't locate my prior post).
The facility is BYO, no corkage. We drank R de Ruinart.
