A great anytime place, Le Cartet has a spacious interior where you can stop in for crepes or eggs with smoked salmon or duck's breast in the morning, sandwiches or salads for lunch, and coffee and desserts at other times. There's also a small shop that sells artisanal chocolates, Québec jams and cheeses, and delicious brioche.
You can always get your meal to go and head to the waterfront.
