I love Sprouts.
The store is never too busy and it's always clean. They have so many great and healthy options to choose from. Their organic food is cheaper than whole foods and just as good. Their produce tends to last longer as well.
I come here every few weeks to stock up on all of the health products I have trouble finding elsewhere (Like Walden Farms!!)
They also have boars head deli meat which is pretty hard to find in Vegas!
This is a great food store.
