I was introduced to this place via a Yelp Elite Event in January 2017 "Celebration Elite au Festin du Capitaine" and since that time, I've been there twice.
I'm a big seafood lover so I really like this place. The only thing that I've ordered both times (excluding any side dishes) was the 1 pound of Shrimps in Captain Boil sauce which I selected mildly spicy. The shrimps were full shrimps (with head) so it was somewhat messy to eat (peeling the shell, etc.).
I went to Captain's Boil both times during my lunch and I found service to be relatively quick. However, since it takes me ~15 minutes to get there from where I work and another ~15 minutes to get back to work, even though I found service to be fast, I only went there when I didn't have to work because of the time required for me to go there and to get back to work (and with a limited amount of time for lunch). There were not a lot of people on the days that I went there for lunch.
A lot of the seafood come out in clear plastic bags. This applies to the pound of shrimps that I ordered as well. For one of my visits, I asked them to add a piece of corn in the bag. Both the shrimps and the corn were excellent in the Captain Boil sauce. My only thoughts on the corn is that I was expecting a full corn maybe broken up into 2 or 3 pieces but instead there was only a piece of corn which I would estimate at maybe being 1/3 or 1/4 of the entire corn. You must love garlic if you ask for the Captain Boil sauce but there are other sauces that they offer. In terms of the level of spicy, I found mild to be spicy enough for me. It wasn't at the point that I needed water after every shrimp.
I found the washroom to be clean and well maintained. The only thing was that I thought that the soap dispenser near the sink table required more soap but they had another soap dispenser near the bathroom wall which had soap in it. They also had some mouthwash in the washroom which is great considering that the Captain Boil sauce had a fair amount of garlic which I liked.
This place is somewhat pricey for a lunch (but probably not for a dinner) and is a great place for sharing bags of different seafood with friends. The thing with their menu is that a lot of the seafood items are marked as "seasonal pricing" so if you want to know the price you will need to ask. I asked about the lobster and I was informed that it was $45 and was a fairly large lobster which I'm assuming is about 2 pounds.
Service-wise, I found that the service was okay both times that I was there. They refilled my water during my meal without me having to ask.
