Restaurant that forces customers to sign

I found this video and I feel very torn about it. It's about a restaurant in Canada where all the workers a deaf and when customers come in they have to speak only in sign language. It has created a lot of jobs for the deaf community there but it makes me uncomfortable that people are coming to eat there to have the "deaf experience".
