I've been to Coyotes games and a couple of concerts at Jobing.com arena, so I feel that justifies a review...
Despite an awful location (in my opinion) because it's on the other side of the Valley from me, the facility itself is pretty impressive. I spent time awhile back working at Philips Arena in Atlanta (worth a trip if you haven't been), so I have something I know well to compare it to...
The layout works, the bathrooms are decent (as bathrooms go) - lots of stalls, clean and plenty of toilet paper... and the concession areas are spread out just enough as well (although expensive as can be but that's what you get at most public venues).
We went to the Bruce Springsteen concert most recently and acoustic and lighting was top notch - we had a blast!
