We have eaten at both and the easy choice is Boma! We had a very nice meal at Jiko, but with kids, the choice is easy....and it is Boma. Boma is more affordable and has a selection of food that will please everyone. Jiko is ideal for a 'parents' only meal out and it will be more expensive than Boma. Don't get me wrong, both are very good but I even prefer Boma overall for the variety of tastes you will be able to enjoy while there!
