I live in Las Vegas. There is a rather large Whole Foods on Las Vegas Blvd (LVB). Take the strip south past Mandalay Bay almost to the 215 (about 2 miles). There is a large shopping center on the right, WF faces LVB. The only thing you can't find there is raw milk and butter.
Also, there are plenty of steakhouses that will serve you a very rare steak. You just have to tell the waiter just how rare you are talking about. I usually explain to them that I normally just eat raw steak out of the package and they get the idea.
Worst comes to worst, you can always substitute some cooked paleo. I hate to do it, but like right now I'm in FL until Thursday. I have found as long as I keep it paleo, and make sure to mix in raw food when I have the opportunity, I do alright. In fact, there's no health stores here that serve all natural or organic meat, so I just have to make do.
