Fish and Chips, Available in Gluten-free

about us

Jessica and I still remember our first opening day on March 10th 2008. We didn’t know which fish is which at the time. We learned. There was not enough money, there were language issues and we had no experience. We were real babies in this business. There was always something that went wrong but we pressed on. You, our customers, were always there to encourage us, and you were always so kind to us….

Love this place.

Best wings in town, service isn't amazingggggg like nobody will greet you at the door and if it seems full you'll probably be standing there until a table clears and you'll have to claim it yourself but I really don't care about that. I had fun here, once we were seated they were pretty attentive. I kept boasting about the wings!!

The best fish and chips I have ever had.

The best british fish and chips I have ever had. Nothing can compare. My wife is celiac and they do gluten free as well. If you are looking for great fish and chips look no further.

Love this place. Haddock and Chips is my favourite.

Love this place. Haddock and Chips is my favourite. They always have enough of the tartar sauce as well. I always get the special on Friday for two people and it is a great deal. The fish is very large and has lots of meat on it. Much better than other places where you have to eat an inch of batter before you get a small piece of fish.

The chicken strips were probably the best I’ve ever had! The owner is so nice and friendly. Fish and chips portions were also really big and we’re also a hit.

Pianist Jessica

I was born in South Korea and grew up in a Christian family. I was a church pianist in Korea and England however I didn't have a steady opportunity to play piano in church when immigrated to Canada. Because I was so eager to play piano, I found seniors' residences, long-term care homes and hospitals to share my talent...
