Yak and Yeti seems the simpler choice if you're already at AK. I prefer Tiffins as far as food quality goes, but for kids the menu might be a little high-brow - Yak and Yeti is more of a chain-restaurant quality level, aka consistent and decent, with a wide menu selection that should work for most kids too.
I really enjoyed Skipper's when it first opened, went 3 or 4 more times after - found quality has always been fine, but the menu hasn't changed much since it opened and is limited, so I haven't really been tempted to go back again the past few years. I hope maybe they broaden or change the menu at some point, to make it fresh and interesting again.
