Also, if you are a regular, if you go into the official change shop and tell them you are a regular, they will give you a bit better rate and they also give you a card to bring in next time. We found that Zumrut Jewellery was not giving as good a rate as the Change Shop. Also, none the shops can advertise a rate outside, because against the law to change money anywhere except the Official Change Shops and the Banks. So, you would have to go to Zurmut and ask him what rate he was giving.
