There is no instructions here and no menu, so here's the low-down: walk to the back of the restaurant where the fresh fish is behind a glass window, choose a type of fish you want (which can then be baked with spices or deep fried in batter). You can add veges to the fish as you like. You can also get shrimp in garlic sauce or deep fried, and you can get calamari and lobster as well. Then you order side dishes like rice or potato wedges (which are amazing!) and then take a number and get seated. All of the seafood is charged by weight and cooked without an extra fee.
We tried the turbot fried, the basa baked, the garlic shrimp, the calamari, the rice, and the potato wedges. Everything was really really delicious (except the rice was quite plain, but worked with the baked fish). Definitely would go back the next time I go to Montreal!!
