Local Henderson Whole Foods for all the local Green Valley Ranch residents! I don't think they have While Foods in Las Vegas so this may be the closest one if you are staying on the strip but not one hundred percent sure so don't quote me on that!
They carry a wide variety of dairy free and gluten free products which I'm thankful for considering I am intolerant to both of those!
They have a salad bar as well as cafeteria and a coffee shop and they do fresh juices and smoothies as well. So you can do your shopping here and/or stop in for a decent lunch with any health conscious folk and you'll have yourself a grand old time.
