I absolutely love yorkville whole foods market!! Its my favourite place to walk to in the mornings because everything in there looks so fresh! I don't usually go there if I'm buying a lot of groceries, but for specialty/health items and brands they're one of my first choices. My favourite part is probably the "market" atmosphere of the store with a salad bar, fresh cheese and tons of fruits and veggies. Plus everything is always clean and they make healthy food look delicious. Although it is a bit pricey, so is organic/health food in general- at least with whole foods you know it has a good name whereas some other Toronto health stores have questionable produce that I wouldn't feed to my friends.
Minus one star for some pricey items, not the most economical place to buy groceries.
