I took the culinary tour at AKL. I think it will help you get the most out of your dining experiences at AKL.
They took us into Jiko first and talked about the philosophy behind the restaurant's decor which was quite interesting to hear, actually. Then they sat us down at the counter that faces the kitchen. They reviewed the menu with us, describing each dish in detail. They let us sample one of their appetizers. I think it was called the "Taste of Africa" - it consisted of several different kinds of flatbread and three delicious dips.
Then they took us into Boma and one of the chefs walked us along the serving areas and described the types of food they serve there and how the food selection varies from day to day. He let us sample one of the soups and then.... gave us each a zebra dome!! Yum!
The tour doesn't take too long (45 minutes?). It is especially helpful if you have never dined at Boma or Jiko before because you will get a lot of info about the food that is offered at each restaurant. But even if you have been to one or both restaurants, you will still learn something. I had already eaten at both restaurants a few times before taking the tour and was surprised by a few things. For example, I didn't know that Boma always offers a vegetarian soup option every night. I am a vegetarian so that was very useful info!
The tour group was small -- 8 of us, all adults. I don't think kids would be interested in this tour, however, unless they are dreaming of being a chef some day! They will have a lot more fun out by the pool or doing the cookie decorating or the animal tracking. But for the adults in the party who want to get the most out of their visits to Jiko or Boma, it's worthwhile.
