I love the food here and we always go to Ka Chi for Korean food.
It's a family restaurant and service is usually as a restaurant, you order, they bring you food.
One thing about Ka Chi is that they get really whinny about the tips you give or how much you give. They don't go up and beyond for service but get annoyed and will call you on it.
I think it's very rude because tips is something given to you based on your service.
