Personally I've had really great experiences with King Sea. I really like the orange chicken and chow mein there. Their sugar biscuits are pretty good too.

All the food I had was bland, General Tao Chicken was tough, and over cooked. Pot Stickers were cold and dipping sauce was very sour. Would not waste my money a second time.

I posted a review for this restaurant on their old page and just now realized it....oops. So here it is in a nutshell: The food here is still THE best in and around Sioux City if you're looking for Chinese. On the downside, they only do delivery and carry-out. But on the plus side delivery is MUCH faster than it used to be and the food is always fresh and hot. Eating from a menu is so much better than some of those buffet style restaurants, and it's actually cheaper too (I never feel like I get much value at buffets because I'm not a big eater). When you order their dinner size meals the portions are more than enough to fill your plate and then some. I would recommend their Orange chicken because nobody in town has a recipe as good as theirs. If you like spicy, try the szechuan beef.
