Chako is decent for what it offers in the suburbs. Dinner includes sushi for order as well as the AYCE grilling. Go for lunch or after 10pm when they offer the cheap late night pricing if you're not willing to pay over 20 for the meal. Drinks are not included in the pricing.
The meats are pretty much marinated in the same sauce. It's flavourful but they all taste the same. Vegetables include zucchini and peppers which aren't seasoned. Pineapple was available for grilling as well - these weren't ripe at all. The seafood is sometimes okay but they tend to be quite fishy in taste so I don't really recommend them. Side dishes are included as well - kimchi, pickled radishes, bean sprouts, etc. They're pretty good and help balance the primarily meat filled meal. Sushi selection is very limited so don't expect AYCE sushi selection. The rolls are comparable to most AYCE sushi rolls - too much rice, not enough content.
It's not a bad place but it's not great. Decent if you're looking for grilled meats and not wanting to travel too far. Nice decor. I found the service to be pretty good but maybe I just got lucky judging from the other reviews.
