2nd time coming to a Captains Boil ever and I have to say it's good only if you believe it's worth the mess. I got shrimp and also had a chance to try the mussels. I love the Captain's Boil sauce because it combines all 3 flavours offered. The CB sauce is not too salty and is very smooth -- great for seafood. In terms of spice, anyone who is accustomed to regular hot sauce (tabasco or sriracha) Medium is fine and you can probably handle the hottest.
I also tried the fried cajun rice (a little spicy) on the side -- it's very delicious and well seasoned, would recommend it! I also suggest adding corn into the mix you choose, it's great mixed with the seasoning.
Overall an interesting experience eating with your hands... if you have the patience for it haha. They do however have options that don't require you to eat with your hands. Probably would only come back if it were for an occasion.
