They are rude, very limited glasses choice and I waited standing in the shop for almost 15 minutes while all sales assistant were doing their own business. When finally I got asked if I needed something… dooooh… they told me to take an appointment for the optician visit. WHOOOOT? Any other shop in Amsterdam would just sit you down, maybe ask you to wait, but then you get your eye sight checked asap so they can sell you the glasses. Really disappointed. Never again.
