Longo's!
Visited twice while in town for the weekend and instantly became a fan.
Huge store, well laid out and clean!
Reminded me in many ways of a Whole Foods with its extensive bakery section and prepared foods.
There weren't as many checkout lanes as I would have expected for a grocery store downtown but that wasn't a big deal.
Prices for the items we picked up were on point with anything we'd spend in the States - 2 liter bottle of Ginger Ale was about $1.25, 5 pack of croissants was $4.99 (both CAD).
I imagine I'd shop here often if I lived in downtown Toronto.
