I went here a couple of times, and I always thought Chako was just average and nothing special.
The meats are very thick, so it takes a while for it to cook properly, which is a downside. However, the prices were okay, and I liked how big and spacious the restaurant is (compared to how cramped up other Korean BBQ places are).
The only thing that I really enjoy is the mango ice cream for dessert HAHA but mango ice cream is all the same everywhere!
