Kaju Tofu Restaurant-Garden Grove, CA. I have been going to this restaurant for years. It has gone through a couple of management changes but overall it still is my favorite Soon Doo Boo place. Soon Doo Boo/Sundubu is Korean Soft Tofu Soup. It is a spicy piping hot boiling broth that can be served with Beef, Pork, Octopus, Seafood, Kimchee and even Ham and Cheese. This is my favorite Soon Doo Boo place even though the quality might not be as top notch as it was back in the day. It still serves very high quality Tofu Soup, it has great ban chan (appetizers), their spicy cucumbers are to die for, they have a free Icee machine with two flavors and they have wooden statues of men with penis heads! Need I say more. Love, Peace and Soon Doo Boo grease.
