The PEI mussels are the best. It is such a welcoming environment. All of the staff are friendly and helpful. Everything is made fresh and the quality of the seafood is very apparent.

We started off with the delicious muscle appetizer with coconut curry sauce. The toasted bread allowed us to finish all of the sauce! We both enjoyed the market fish with salad and rice. I had the cod which was crispy and moist and my husband had the sea bass also prepared the same way. We can't wait to go back!

This restaurant is a GEM. Wonderful food, incredible service. Everyone is super friendly and efficient. The atmosphere is inviting and modern and clean. We loved every minute of it. I also got a text from the manager after saying how nice it was to have us there and if we needed anything for the future to text. It was incredibly personable and an extra touch that makes me want to come back. And I can't say enough about the menu and the quality of the food. Simply delish.
