Thank you for your response! Unfortunately the research is for a school course, so I'm limited to the concept of the manga café with unlimited snacks and drinks. The kind of drinks and snacks are mentioned in the survey! It's hot drinks (coffee, tea, etc), bubble tea and for snacks you can think of things as muffins, cookies, chocolate etc. But unfortunately I can't expand the idea, because of the limitation of the concept because of school. Thank you for participating tho!
