The Kona Grill at the Chandler Mall is the location that I prefer! Nicer servers and for some reason unbeknownst to me, better food.
As someone previously said, good luck with getting a table during happy hour here, but sometimes you luck out and get a decent seating. The seafood here seems fresher to me than the one at Scottsdale, who knows why. It's also a place to people watch if you're sitting at the patio, but then again, that's sorta creepy.
Other than that, it's a recommendable place if you just want to throw back a few drinks over good food.
