Bonterra Trattoria is amazing Italian cuisine in a relaxed funky atmosphere.
The interior is cozy in the best sense of the word and the staff make you feel right at home. Then the food arrived and nothing else mattered - succulent lamb, heavenly carbonara, soft, fresh mozzarella, and (by far) the best meal on the table was the gnocchi. It was melt-in-your-mouth delicious - just beyond superb and I will be back just for that dish.
If you are visiting Calgary this should be on your must try list of restaurants.
