I too would love a rec for this. Have been disappointed many times in many venues. The standard for me personally was set by the original owners and chefs at Ci Vediamo in the Beaches, sometime back in the 20th century. Perfect al dente spaghetti, lots of fresh clams, a white wine sauce that managed to be both delicate and assertive at the same time, generous amounts of flat-leaf parsley and fresh garlic, served piping hot. But that standard didn't last long (maybe owing to the departure of a chef??), and subsequent changes of ownership made things much, much worse, IMO anyway.
Mercatto on Toronto Street used to do a good (not outstanding but credible) version, but I haven't been there for a while. Up-to-date recommendations for this simple yet apparently hard-to-achieve dish would be much appreciated.
