I missed the Fish House. It used to be at DVP and Sheppard. It then moved to 7503 Woodbine Ave. then it disappeared. Now, there's Diana's. Very cool place. Oysters galore! Great wait staff. Very knowledgeable. You can make a meal just out of the appetizers.
Come during the week! Ask for Steven!
After my third visit, I can recommend the weekly oyster special and any appetizer listed.
