OK, so the guy claiming that employees at this location are rude....maybe I got to them after they saw that review because the two times I was in they were some of the friendliest people I had ever encountered in health food stores in Vegas. They offered answers about products, they wrote stuff down for me to look up later, they were excited that I came to them via groupon...they didn't try to upsell or push products on me. As a student of nutrition I am kind of on the lookout for people who don't know their health info, but they passed all my questions with flying colors. I had a very different experience than this other reviewer....
The only down point is that the products I was purchasing were a little (a lot) more expensive here than online, etc. But that said, they had just about every supplement on the market today and the employees I interacted with (man, Brett?, and a blonde woman) were pleasant and knowledgeable giving customer service which you can't really get on amazon or at GNC.
