We did not have a reservation for this restaurant (I highly recommend one though!) as I was drawn to it due to the advertisement of Mussels on the menu. Having recently enjoyed some amazing Italian Mussels in Monterosso, I wanted to see if Canadian restaurants could compare.
The Mussels & Clams appetizer was very good (not Italy quality, but a very close comparison)! The mussels were tender, in a subtle tomato spice sauce.
My linguine e gambero was great, with large, tender shrimp. My boyfriend tried the gnocchi with sausage and pork bolognese, which he was very fond of.
The food was superb, the restaurant ambiance intimate and light, and the staff were extremely friendly and helpful. We definitely appreciated them fitting us in without that reservation!

Delicious food! Had the gnocchi with pesto and was in heaven. Wine selections were wonderful. Atmosphere enjoyable. All in all, a really nice choice for dinner.

Great food and marvellous service. Not the cheapest place in Jasper but well worth it if you want a nice relaxing meal.

I had the pesto chicken gnocchi and my wife had the cannelloni and they were both excellent. Portions were generous - I couldn't finish mine. We shared the salad and that was enough for two. Desert looked good, but we were too full. Service was very good. We liked it so much that we went back for the breakfast special in the morning. That was also good.

We searched high and low for a nice restaurant in Jasper and after reviewing the menus outside the restaurants, coupled with the positive reviews on Trip Advisor, we visited Cassio's last night. It was so good that we are going back tonight. A little pricey but that was our choice with wine, appetizer and dessert. But then again even a hamburger in Canada is pricey no matter where you go. At least here, the portions are worth it. I usually don't order ravioli because you never get enough but at Cassio's I had a problem trying to finish the amount I was served. And, the butternut squash ravioli were fabulous. Our waitress, Tricia, was the best! TOTALLY enjoyed it!
