We had a wonderful experience at Le Filet. We sat at the bar on a moderately busy Wednesday night, which I'd highly suggest, since it gives you a great view into the open kitchen. Our server, Steven, was extremely helpful and attentive all evening.
To start, I'd highly recommend the tuna tartare. We also had the kampachi and the oysters three ways. The plain oysters weren't much to write home about, but the jalapeño/maple chip and the miso gratin were excellent. The miso gratin in particular was a totally unique preparation and a very pleasant surprise.
For mains, we had the pork loin and scallops, a delicious and unique take on surf and turf. I usually shy away from pork when eating out, and this one still stood out. The seafood linguine with fried onions was outstanding. For dessert, you can't miss the maple square.
All in all, the hospitality and the quality of the food at Le Filet were world class. It's easy to see why this place has been around for 15+ years, and I'll definitely be back the next time I visit Montreal.
