As I understand this shop has exclusive eyewear. A friend recommended them to me and My first trip in just to see what they had and if I could afford glasses from them. I don't think they like folks coming in to browse. But I have to say when I returned to buy the glasses I had seen in my first trip I have been treated very well with great respect and customer care.
I think that they need customer care improvement in dealing with anyone who happens to walk in to the store as it is in a shopping trendy area and does not have any signage that suggests an appointment. Perhaps another polite sign that asks for permission to take a photo or stating their policy is no photos. But despite my first visit being a little off putting I am happy with the service as a customer.
