Gallery Baraka is the one place in Lamu town where you can find high quality African jewelry and crafts from all over of the continent. The items are well made and well curated. You will pay more for here of course but if you want to return home with something special, then this is the place to stop into.
Kate, the owner is a bit stiff and she will ask you to take off your shoes upon entry but I found it well worth the small and cultural inconvenience.
Whisper's Cafe is next door through the back garden.
