Not strictly vegetarian, Art Square Cafe has enough meat-free options on its menu to warrant a mention. Directly across Dundas Street from the AGO, 16" folded, stuffed crepes (either plain or buckwheat) are served in an artsy gallery setting. Beverages are notable: Illy coffee concoctions and a fanciful tea menu. A liquor license means you can have a glass of wine with that. Open ten to ten every day at a really convenient central location.
