I come here regularly to buy my vitamins and other "health food" stuff. the bulk bins are well priced and include much higher quality ingredients than at the mass market bulk bin stores. They also have a good selection of specialized food items such as gluten free, herbal, vegetarian, sugar free, etc.
If I am in the Kensington Market, this is a sure stop for me. Tutti Frutti is a little better priced on some items than Essence of Life, but in truth I shop at both places because of the selection in both.
