My wife and I have lived here over a year and finally tried this place to see how it measured up! I've seen comparisons to In N Out and here's what I think.
I liked the burger,it was cooked perfectly and I like the fact that they obviously use beef with some fat in it which keeps it juicy! The crinkle cut fries are great! I got mine with melted cheese but recommend skipping the cheese,better without it! I also didn't like the "Shack Sauce" had a weird taste I couldn't figure out. I'd come here again but would skip the sauce and get plain fries! Shakes were great!
For those who want a comparison to In N Out, I'm from California and can say the Burgers are about equal with In N Out much cheaper but Shake Shack fries are MUCH BETTER than In N Out !!!
