I have had "healthy" food from the Bay Area and I might have to say that I may have a slightly distorted high-standard but a standard nonetheless. With regards to Rachel's Kitchen, I would say that their food is mediocre. It is pretty ordinary and slightly pricey for what you do get. The juice is watered down and not as full/rich as I am used to (or how it should be).
The one thing that I would go back for (and have) is the Incredible Hulk shake. I am slightly lactose-intolerant so I appreciate when some food is dairy free. This one comes with silken tofu, peanut butter, honey, and banana and tastes like a PB and banana sandwich - THE BEST. Other than that, Rachel's is just meh to me.
