We did this 11/30/10. I made the reservation 6 months out and paid when we checked in on the day of the safari. We met in the little waiting area by Jiko. There were 10 of us total. We walked out to the front of AKL and climbed aboard our truck. Even if someone is short, the truck stops several times and you are able to stand up and move from side to side and take photos. The guide was one of the animal keepers and she was great. The driver was also an animal keeper. We learned so much about many of the animals, some had been banished from Kilimanjaro safari because of behavior issues, for example, the Hartnel Mtn. zebras on our savannah had only been put there the day before, why the one Ankole cattle on Arusha always tilts his head (I forget his name,) that type of thing. I wish I'd brought a little notebook. She told us about the situation in their native land for some of the animals, the breeding programs, personalities, names. etc.. For a dedicated nature/nat'l geographic phobe like me it was wonderful.
Dinner at Jiko followed, our group had such a great time we overstayed and some of us wandered out to the outdoor fire to continue our chatting. The Chef came out to talk about each course along with a trainee chef. I'm not a huge food person and we had a number of signature dinners that trip, of which Jiko was the first, so I don't remember much about the food - flat breads, definately, filet as one of the entrees was outstanding. Some items came out on shared plates, but many were presented individually, as well. I believe I left a tip, but can't recall - I know it sounds like I was looped, but I didn't try any of the wines, although they were offered with each course and one of the deserts came in an adult or kid version (w/ or w/out alcohol added.)
When we next stay @ AKL, we'll definately do this again and this time I'm taking a notebook to make notes about whatever animals are on the savannah I'm on. I think it's smart to do the safari early in your stay so that you have the info. on the animals in your savannah that you'll be seeing for the next several days. I have photos, but don't know how to post them - sorry.
And whether we are @ AKL or not, Jiko is now on our ever increasing must eat there list of restaurants.
I can say it's a lovely thing to do and we really enjoyed the experience.
