Lobster Royale is very good but one should also consider The Lobster Trap on Avenue Road south of Highway 401. I believe that the owner or chef of Lobster Royale used to work at the Lobster Trap. Also the best lobster bisque in Toronto is not at a lobster restaurant. Try Richlee's Restaurant on Avenue Road across from the Lobster Trap.
Lobster is not mentioned because it is almost impossible to serve "good" lobster so far away from the sea.
A restaurant has to fly just enough lobsters in from the coast everyday and serve them that evening to the clients - better plan on paying $100+ per good crustacean here (if a restaurant can survive doing that).
The two restaurants cited "tank" their lobsters. That means these creatures are swimming in a bath of their own secretions for days on end until either they die or cooked. You can *definitely* taste tanked lobsters! That's why it is good to have strong garlic butter and/or black bean sauce when dining on affordable lobsters in TO :-(
