There are two places called Tutti Frutti - one is a garish, overpriced candy store and the other is a reliable health and specialty foods store in the heart of Kensington, a few doors away from its 'rival' Essence Of Life Organics (think Global Cheese vs. Cheese Magic). It's worth a price check between the two stores, but like other reviews of EoL have said, you can do a complete grocery run if you combine the inventory of both stores.
I usually stock up on protein powders, cheap soy milk and ice cream at Essence Of Life, and leave the bulk stuff to Tutti Frutti. They have a ridiculous selection of "weirdo powders" and roots, the likes of which would startle any naturopath.
In fact, whenever my naturopath sends me away with a laundry list of herbs to buy for tea, I head straight to Tutti Frutti to pick them up. They also have quality spirulina, probiotics and gluten-free flour in bulk as well.
