I go to Bluestone pretty well EVERYTIME I head to Toronto - My brother has two kids and this place works well for the family.
Despite being a wine bar atmostphere, it's a great place to get consistent, DELICIOUS weekend brunch. Prices are a little high, but you're paying for quality ingredients and an attentive staff. I've never had a bad meal here or bad experience for that matter!
Look around and you're almost overwhelmed by the wine bottles in this joint - I've never dined here in the evening so I've skipped their wine selection but their bloody caesars are pretty damn good!
Great place for adult as well as families. My brother and sis-in-law's big concerns when taking the kids out is cleanliness as well as noise level and this place is wonderful for both!
