I've been to the Korea House quite a few times as my family loves Korean bbq. The staff is always very nice and the service is prompt, however, the building itself is very, very cold. It does tend to heat up after a crowd gathers but beware if you're going to be the first one seated at lunch time. The staff is great with kids. Unfortunately, they have no flexibility in substituting side dishes, soups, etc. which is surprising considering their combination offerings are SO expensive. There is no lunch menu and no early bird pricing. I would recommend trying one of the smaller places around town where the service is more flexible and you can eat without having to wear your coat through dinner.
Pros: Fun atmosphere
Cons: Cold (brr!), pricey and no substitutions
