This tofu house is the best Korean tofu soup you can find in the local area. There are quite a few Koreans living in Fullerton. For better tofu, you probably need to go down to Korean Town in Garden Grove. I have been here a few times and the restaurant is always busy. Service is not great but it is to be expected.
I am going to concentrate my review on the to-go menu. Food to go is made quickly (10-15 minutes). The kimchi is sparse it is hard to pack more than 5-6 items to-go. The tofu soup is flavorful and hot. Prices are a little higher but you have to consider the area.
