I had read about this place on happycow, and here's my Essential Living Foods review.
I've been to this showroom a few times and bought some stuff. From time to time, the stock changes, and new products are introduced. Like one time, I found and bought dehydrated & seasoned kale chips (okay taste).
Basically the food stuff sold at Essential Living Foods stockroom is what they sell online: raw and organic superfood stuff like nuts, oils, olives, goji berries, raw cacao and raw chocolate snacks, brazil nut protein, etc...
You can also find their products at nearby health food stores (Santa Monica Co-op, Whole Foods). The selection is decent and the prices are reasonable.
Beware: call ahead to confirm that they will be open on the day you wish to visit. I've been turned away before because they changed their open day policy.
