Chako is an great KBBQ place in Scarborough; one of the best in my area. However, compared to other k-grill places I've been too, it's just slightly above average.
The food is pretty good. I LOVE the chicken. Even though it takes a relatively long time to cook, it's definitely worth it. You can't go wrong with the other meats and veggies either. The atmosphere is pretty nice, but it does get loud.
Chako is perfect if you're looking to stuff yourself for a pretty good price. Coming for lunch or late at night is definitely recommended. I've been to Chako about 5 times now and I've never been unsatisfied.
