We ordered some raw oysters, a clam chowder and a seafood platter, which contained an assortment of grilled seafood. The oysters were fresh. I can't give 5 stars to a food where no cooking skills is called for, so the oysters got 4 stars. Seafood platter was a matter of salt, garlic and herbs. Simple. Beautiful. And I can grill it just about as good. Clam chowder? It could be 4 stars in Toronto by comparison. But considering Diana's has access to the freshest clams at cost, I expect something more in line as Boston or Cape Cod clam chowder. No such luck on my visit. My recommendation is to stick to raw oysters if you come here.
In terms of pricing, it is justifiably expensive. There is a premium on top shelved, fresh seafood in Toronto.
