I ate at this location once at 1am while in Vegas. I ordered a single animal style, and well done fries (plain on this visit).
The burger was good and fresh. The well done fries, upon first taste, we good. It dawned on me that even though I had ordered well-done fries on my last visit, that clearly they were not well done. These were extremely crispy and oily, and it was a little too much for me.
The food came out in about 10 minutes and it was all piping hot.
If someone were to try to compare both Five Guys and In-N-Out, I think that by far this locations close proximity to Five Guys would make for an excellent head-to-head comparison. Unfortunately, I lack the stomach and the time to do that.
