I'll be honest: I'm not much of a fast food person. Therefore, I have no real opinions on In-N-Out versus Five Guys since they both actually taste pretty much the same to me. I came to this location because a friend in my group had never had the fabled In-N-Out burger before, and needed to try it while in Vegas.
The restaurant was packed to the nines at 11:30AM on a Friday. We barely managed to snag a table. The wait for the food wasn't too long, though. The burger was decent, but the fries were really disappointing. My fries were soggy and hard to eat--I ate barely half of them. My friends ordered theirs animal style, and the onions were quite undercooked. All in all, this was much more disappointing than my last In-N-Out experience in LA.
