Out of your list, I picked the Tuna appetizer, the Filet entree, and the mousse pyramid for dessert, just because I don't care for pistachio, Off your list, my favorite Jiko appetizer doesn't seem to be on the menu anymore (the duck firecrackers), but the maize and sweet potato tamale would be a close 2nd. I really love the filet and the mac and cheese, but my partner normally orders it, so I get to try the seafood entrees. They used to have a Chilean sea bass cooked in a banana leaf, but it's gone too <sniff>, so I'm thinking about the Maize-crusted seared Pacific sturgeon, the Durban curry shrimp, or the filet for my meal on the 26th. And I agree, the servers at Jiko are some of the most knowledgeable at any restaurant I have eaten, and can answer most any question about the food, wine pairings to have with any entree, etc. etc.
Enjoy!!
