No, but I've been to Momocon.
Basically same thing except probably a little bigger. (?)
I got a sushi pillow there.
And a (don't laugh) naruto ninja headband =D
Village hidden in the mist ftw. (all they had was leaf, sand, sound, mist, and Itachi's headband (leaf with cross through it))
I almost got the sound one, but Haku is just so damn awesome.
