Phoenix Wagyu or Kobe
Are there any restaurants in Phoenix that serve either of these?
... and I would think that J&G Steakhouse would offer it but a quick look at their online menu doesn't show it. Good money says that they probably have it, though - even if it's only a special.

I've never been, but, I would go to Yasu, if I wanted Wagyu.
