Restaurant - For twenty-six years, the Blue Mermaid has been to St. Catharines what 5 star restaurants the world over have been to their cities. Nick and Tom Kosilos, along with several family members working hand in hand, have stayed focused on maintaining the Blue Mermaid's sterling reputation as the premier fine dining seafood and steakhouse facility in St. Catharines and how successful they have been. The Blue Mermaid is still first to mind when it is time for an ultimate dining experience.
