What you have heard about In-N-Out is true. It really is that good. Now please take into consideration that I had been drinking vodka sodas for 3 hours prior to consumption, but it's Vegas so it just elevates the experience!
There was a line but it went quickly. I ordered what my west coast friends recommended fries "animal style" and a burger "protein style" aka no bun. All the ingredients tasted fresh and the burger was really all about the meat. The sauce was delicious!
Now if there was a Steak and Shake right next door, it might a coin toss between the two.
