I learned about the eat-shrimp/crawfish-in-a-bag initially from Kicking Crab in Westminster, CA. Good eat!
I read the reviews for similar establishments in GTA. I will sua that it is not quite that Louisiana flavour but it ain't bad either.
Never ate at the restaurant itself because of the following reasons:
1. Cheaper to eat at home
2. Easier to eat with cleaner hands
3. Seafood is already more expensive here than our neighbour down south.
4. You can add extra spices at home to make it taste almost similar to the Louisiana flavour.
5. Eat the extra sauce with rice/potatoes.
6. Wait time for take out is ten minutes. Then you are ready to eat! They give us the bibs and gloves anyways, which we don't use.
Will I come again? -I did.
