I was in this new location Friday between the lunch and dinner rushes. The line wasn't too long but it was confusing because you can enter from inside the mall and outside through the restaurant's front door. I hope they can better define where the ordering line starts.
The menu is pretty much the same as the Shake Shack locations that I've been to in New York and Miami. The employees are very nice and well trained.
I had the Smoke Shack burger and it's tasty with the BBQ sauce and bacon. I also tried the Dust Devil concrete which is special for AZ and is very good with it's salted caramel and other ingredients.
