Calgary Co-Op Wines and Spirits does not only host a large selection of wines and alcohol, but the space is visually appealing. It is a new building, with new fixtures and the staff are friendly as well.
This is one of 3 local liquor stores in my area, so I generally go there when someone recommends a bottle of wine, and I want to make sure I only need to make one stop. Calgary Co-Op Wines & Spirits almost always has what I am looking for due to their large selection.
The price point seems to be reasonable. A few dollars more than another liquor store in the area, but I don't mind paying that for the convenience of knowing that what I am looking for is going to be there. I'd rather make one stop than many.
Quarry Park also has the advantage of lots of parking. The mall is relatively new, so it is not insane yet. I value being able to get in and out quickly.
