Orso Trattoria is set inside the Jasper Park Lodge, which sits on Lake Beauvert and is one of the best Jasper hotels. The resort's grounds are superb and a delightful place to spend an evening if you're not staying at the lodge.
It's an Italian fine dining restaurant in Jasper with an extensive wine menu to pair with dinner. Menu items include burrata, duck leg, ravioli, braised leeks, ragu, and a selection of grilled meats. The menu can be ordered ala carte or as a prix fixe 3-course menu.
In the summer, you can sit outside and enjoy the atmosphere with a delicious tapas-inspired menu. They also offer a wide selection of wines and excellent main course pairings. It's also a great place to head for breakfast in Jasper, definitely one of those mimosas on Sunday types of places. Reservations recommended.
