The Dundas Street Grille is, in my opinion, one of the best places for brunch in Etobicoke; it's got that very old school Toronto vibe about it. Please keep in mind that it is a diner, so don't expect anything too fancy as the décor is a bit dated.
We've never really had an issue getting parking or a table as the service is pretty quick. The wait staff are so friendly and attentive as well. One thing we like to order is the Eggs Blackstone - it's basically Eggs Benedict but with swapped with bacon (instead of ham) and rye toast (instead of an english muffin) - so yummy and about $8.00 or so! My husband likes to always get the french onion soup; it's not bad and, I think, about $3.00 - very good bang for your buck.
