We ordered the Small Ocean, & it was more than enough for two people. Everything was fresh & absolutely delicious. The staff were also kind & attentive 🤍
We had an amazing experience at Mr. Cajun! The staff was incredibly friendly & welcoming, which made our visit even more enjoyable. We had never tried seafood prepared in this style before, & it was such a unique & delicious experience. Everything we ordered was flavorful, fresh, & exciting. We truly enjoyed every moment & would definitely come back again. Highly recommended!
Went to Mr Cajun & had a really good experience overall.
The server was super friendly & made everything feel easy from the moment we sat down. Service was quick, but still relaxed, not rushed at all.
I ordered the Petit Ocean & it was honestly a great choice. Big portion, well seasoned, & exactly what you want from a seafood boil: messy, flavourful, & satisfying. It had a nice mix of seafood & everything tasted fresh.
The only thing is it can get a bit pricey depending on what you add, but the portion size kind of makes up for it.
Overall, it's a solid spot if you're craving seafood & want something fun & filling.

A beautiful memory from our Montreal trip.

I recently had the pleasure of dining at Mr Cajun & was absolutely blown away by the quality & flavor of their seafood. From the moment I arrived, the aroma of perfectly seasoned Cajun spices filled the air, setting the stage for an unforgettable meal. I ordered both the shrimp & mussels, & each bite was a celebration of fresh, succulent seafood cooked to perfection. The shrimp were plump & juicy, with just the right amount of heat & seasoning, while the mussels were tender & brimming with a rich, garlicky broth that had me savoring every last drop.
What truly elevated the experience was the exceptional service provided by Oumaima. She greeted me with a warm smile, took the time to explain the menu's specialties, & made thoughtful recommendations based on my taste preferences. Throughout the meal, Oumaima checked in regularly, ensuring my water glass was never empty & that I was fully enjoying each dish. Her genuine enthusiasm for the cuisine & attentive, friendly demeanor made me feel like a valued guest rather than just another customer.
Overall, Mr Cajun's seafood offerings-especially the shrimp & mussels-were top-notch, & Oumaima's outstanding service made the evening even more memorable. I highly recommend this restaurant to anyone craving authentic, flavorful Cajun seafood, & I'll definitely be returning soon. Kudos to the entire team at Mr Cajun, & a special shoutout to Oumaima for making my visit exceptional!
