When we told our Wild Africa Trek tour guides that we were having dinner at Jiko, they made a big deal about it and gushed about wished they could go with us. Even though I'm sure they've eaten there, it made us feel good about our ADR.
We left AK at closing (5pm), and had about an hour or so to kill once we got to AKL. So, we took a little nap on a couch in the lobby. Our ADR was at 7:10pm, and once again we got there a bit early. I don't remember being given a buzzer, but let's say we got seated within 10 minutes, and leave it at that.
Our waiter, Mike, was very friendly. We decided to take the non-alcoholic route, and split a bottle of San Pellegrino. We enjoyed that enough that we ended up ordering it again at a couple of later dinners. I know it seems silly, but a nice sparkling water with lime is a great compliment to all the eating we were doing.
Here are some menu pics:
Before we even got to the food, there was bread:

We both liked this because it was different. The bottom pieces were sweet, with a hint of cinnamon, and we both liked that bread better than the top, which was more of an herb bread.
I was so happy with the cheese plate at Citricos the night before, that I decided to order it again:

I believe that from top to bottom on the menu was left to right on my plate. On the top is apricot jam, some roasted nuts, and honey. Of course, I was in heaven. I would run into the Humboldt Fog again, but it was one of my favorites anyway. Each of these cheeses really did have a distinct taste. I ate the nuts separately, but the jam and the honey made great pairings with some of the sharper cheeses.
For his appetizer, DH ordered the Taste of Africa:

There is an assortment of Naan, both hard and soft, and four dips. DH and I frequent quite a few Indian restaurants where we live, so we've had Naan before. DH never likes the one that's more like a cracker, so he didn't eat that. Also, a couple of the dips were pretty spicy, and he's not big on spicy (hot). He tried to get me to eat some, but I was desperately trying to eat a ton of cheese after having that major snack on the tour just a few hours prior. Sometimes the DxDDP isn't easy
For the main course, Mike made the filet mignon sound irresistable, so that's what DH chose:

Medium well, just like he wanted, and so good that he wouldn't stop talking about it the rest of the trip. If he ordered beef after that, he would always say that it wasn't quite as good as the filet at Jiko, so I'd say that's a ringing endorsement.
I am a huge lamb-lover, and I had planned on ordering it at Jiko before we even left on our trip.

I don't remember if I was asked how I'd like it cooked, but I usually order lamb medium because most chefs won't cook it any longer than that. My mother makes absolutely delicious lamb, and it's always well-done. Because I knew we still had dessert coming, I didn't eat much of the tomato-chickpea salad, but I do recall it had a kick to it. The lamb was good, and I ate as much as possible, but I couldn't finish more than the first piece. Mike kept trying to get me to take it with me, but we knew it wouldn't be any use since we were on the Deluxe plan.
Along with dessert, DH decided he'd like to try a pressed pot of Kenyan coffee, while I asked for vanilla rooibos tea:

In the background of the first picture, you can see that Jiko does their loose-leaf tea in a pot with a metal strainer at the top, rather than in a press pot. I found out later there was a good reason, but at this point I was just glad to have the tea. DH said his coffee was the strongest he'd had in a while, but very tasty. He took the second picture because he was enchanted with the choice of sugar...brown and white cubes! The little pots in back are pots of honey! Oh, and btw, the vanilla rooibos tea, with a little milk and honey, was absolutely the best tea I've ever had. I subsequently tried to order it wherever I could. Today, I tried the Starbucks version for the first time, and it just wasn't the same. Again, there was no additional charge for the coffee or the tea.
For my dessert, I wanted to try the Cape Malva pudding because it was exotic, and it came with vanilla custard and mango/apricot sorbet. Those are some of my favorite flavors!

This truly didn't disappoint. The cake was sweet, with a rich taste, but the sorbet helped offset that, and the flavors perfectly complimented each other. Plus, it wasn't too big, which was perfect after a whole day of eating big.
DH had the Tanzanian chocolate and cherry dessert:

He says it was delicious...I got a taste, and have to concur. I mean, look at it! You can tell it's rich, chocolate-y heaven.
On each trip, there was at least one time where a waiter would see us taking pics of the food, and offer to take one of us, so here we are right before we took the first bite of dessert greatness:
Total OOP cost before tip? $140.08
We sat down around 7:10, and we got the check at 9:08.
Atmosphere? Dark, but in a good way. We loved the decor, and it never seemed crowded or loud. A definite 4.5.
Service? Mike was nice and we had some good conversation, but sometimes he would leave us hanging a little longer than we liked. Also, I noticed another server was offering people hot towels when they sat down, but we didn't get any. Maybe it's because we didn't dress up a lot? We came from being in AK all day, so we did what we could. I guess this is a 3.5, since there wasn't anything too bad about it.
Food? 4.5, 'nuff said.
Overall rating? We can't wait to go back!!!
