As a substitute, this place is quiet and calm. The policy is very strict among students. They must wear uniforms, stay in line, eat lunch quietly while everyone facing the same wall and only use the restroom when they are allowed to. I dealt with smaller group of rowdy students, at least 5. It is easier to manage a very small group but at the same time, you have to repeat yourself to get them to remain quiet. The staffs are chill and funny. They are fun to converse with but very serious to students. This is a nice place to substitute if you want to be away from large rowdy schools for a while.
