I'm an egg tart addict. I've had the chance to try egg tarts from all over the GTA and Hong Kong, and this place is my #1 pick.
Egg tarts generally come in two main varieties: flaky pastry crust or butter/cookie crust. Too often, the pastry crust variety has an overwhelming volume of crust. The end result tastes more of dough than custard. Cookie crust egg tarts usually have a better balance of crust and egg, but obviously cannot provide the same delicate, flaky goodness that only a pastry crust can.
Red Sail Boat does flaky crusts perfectly. The crusts, extremely thin, accentuate and dutifully contain the rich custard within, never overpowering it. In a nutshell, this place makes the Platonic ideal of egg tarts. If anyone reading this disagrees and thinks there's a better egg tart place in Toronto, please message me and let me know!
This review applies only to the egg tarts -- I haven't really tried anything else here.
