Are you into non-authentic Korean style Korean BBQ? By that I mean if you want to experience REAL Korean BQQ (as you would expect if you go to Korea), please go elsewhere because Chako is clearly (and cleverly) meant to serve a different group of people.
While the food is average at best, but for the price you pay, it is hard to find any other place with a better bang for your buck. Do note that ventilation seems to be a bit of an issue so if you are no good with smokey places, then this might not be for you.
