The Lakeview Diner has a long spotty history. Its beautiful interior is a Toronto treasure that's finally been cleaned up with years of crap removed. Along with the Senator and the Swan, these spaces take you back to another era.
As to the food, the new owners have certainly improved on a menu that got ridiculously out of control in past years. A bit on the pricey side but the food is good. I haven't experienced any of the issues some of the other Yelpers have complained about. I've been coming here since the mid-90s and experienced all the changes. This is definitely the best incarnation of the Lakeview to date.
My only complaint is the greens they serve with most dishes. They can be of the slightly wilted variety and the overly tangy house dressing needs modification. They do serve an excellent $4 Ceasar (the drink that is)
The service is excellent and its an old trusted standard amid all the new hipster hangouts on Ossington that won't last the decade. The area parallels Williamsburg, NY just as Manhattanites found out about it and ruined it.
