I'm a Scarborough boy from way back and I know my Scarborough dim sum places back in the 90's and early 2000's. The novelty has worn off and most restaurants for both cost effectiveness and time no longer do push carts.
But then increase quality with that efficiency! Very few places have done this and the places that do, are very expensive.
Blue Lagoon has great dim sum for a moderate price and has all the favorites.
Fantastic dim sum. Above average. I haven't had time to come for their amazing looking lobster and king crab dinners but if the dim sum is any indication, it's going to be great.
