Went to Kaju Tofu restaurant in Irvine this weekend. Great value for great food. About $8 gets you a bowl of soft tofu soup with your choice of various add-ins (beef, seafood, dumplings, etc) and pretty good panchan. The soup, along with rice and panchan, is really enough to feed two people or one hungry person. Service is very friendly and you get the benefit of being able to "buzz" your waitress when you need her with the aid of a call button at your table! (cool)
For the "non-tofu" eaters out there, its really worth a try. Get the delish tofu soup with beef. Just beware, when they ask you how spicy you want it, they arent playing around.
