Hunting coins in Kampala, Uganda

Hello coin collectors - I am going to Africa and will have a couple spare days in Kampala Uganda, and I am looking for sources where I can buy mint sets, or commemorative silver coins, and also East African shilling coins - especially the silver 1 iland 5 shillings. Does anybody know of any good sources in Kampala? Thanks for the help,
Will

There is no information. Maybe explore Central Kampala?
