'The Works' burger chain, I always ordered an 'Olive Oyl' burger.
South Coast Cookhouse in Crystal Beach always saw me ordering a South Coast burger, washed down with a couple of bottles of Molson Stock ale. Even after they took the South Coast off the printed menu, chef would always be able to make one. Sautéed onions over a burger; that's it.
Minor Fisheries in Port Colborne always sees me ordering a 'Lake Erie Combo'. Perch and pickerel.
Once something works, I rarely change.
