Well I really love both and both are in my top five... but Jiko is tied at #2 with CG (afetr only Victoria & Alberts).
Now it can go either way. I think The teens would get a real kick out of AKL if they have never been there. There are night vision goggles to check out the animals after dinner. In terms of menu- more exotic than your place next door but I am sure they can find something. Check out the menus on allearsnet.com.
Flyin fish is laid back and a ton of fun. They will probably get a kick out of the BW at night (games to play, entertainers) the menu is mostly fish but there are a few other things on the menu as well.
Really depends on what you think they wioll like
