Consistently good across the nation! I have too many good memories of Shake Shack from my time living in NYC - waiting in line from the Times Square location, upper east side, LaGuardia airport, Madison Square Park... so it was so nice to be able to get the same burger in Arizona!
The cheeseburger has high quality meat, the Smoke Shack has awesome bacon in it, but my fav is always the Stack Shack which is the cheeseburger plus fried portobello mushroom! The fried portobello surprisingly has cheese inside the batter, so the cheese would flow out of the fried mushroom and melt in your mouth with the cheese burger. Heaven!
We only waited for less than 10mins in line and there were seats available right away at around 7pm on a Saturday night. Good treat after a movie!
We were too full to have the frozen custard. I usually get the coffee or vanilla flavor! Highly recommend! Don't think about calories and just enjoy.
