I have been to Chako a few times to satisfy KBBQ cravings, mainly because it's in the area. The service is fast, communication can be a little difficult at times but overall okay, and I think they can do a better job at cleaning the tables and area. I wouldn't necessarily recommend this place, but also don't know of any other great KBBQ places around the area.
Expect to spend about $70 for two people at dinner time.
