Johnny Rocket's is a mix between a 5&Diner and an In and Out Burger with a dash of Ed Debevic's (May it rest in peace).
Great burgers with good looking fresh ingredients. Shakes that are out of this world. But I've never seen one that wasn't in the mall. This particular location is in Arizona Mills and it's a pretty good sized location. Not one of the largest ones, but it has counter and booth seating. Though, like many other locations, during peak times you can expect to see a line forming outside. We've stood in line before - just for a shake to go.
At this mall one of the other advantages here is that this isn't a part of the official food court. It's pretty much on the other side of the mall. So if you're there and hunger strikes - you don't have to walk to the other side of the mall. And in this mall, that could take you awhile - longer with kids, even longer with window shopping friends.
By the way - they have Boca burgers and Turkey burgers. You want an egg on it? They can make that happen. They also have other sandwiches - from a grilled cheese to a Philly. I suggest ending it all with a Hot Fudge sundae.
And after all that, you'll want to do a few laps of the mall just to breathe again of course. So if you need to leave soon, make sure at least one person in your party has some restraint. Let them get a salad. The rest of you will be too deep in a food coma to be trusted behind the wheel.
