When I go visit my brother and it's just the two of us (or three of us if my wife Sheila F. comes along), we always go here. I wish this place had been open when I used to visit my dad on a regular basis when I was younger so that I could have made some late-night visits on my way home!
The food here is really good--I always get the General Tso's Chicken and it's great...nice and spicy. Portions tend to be pretty generous too.
One bonus about this place is that they don't charge for mustard sauce. Other places in Cleveland charge a quarter or something for it. Sure, it's not a king's ransom...but the free sauce is one of those nice little touches that makes me want to hop on Yelp and review China House in the hopes that it'll drum up some business for them.
