The Saddledome is one of the most recognizable arenas in the world of sports because of it's shape. It goes great with the downtown skyline.
Inside, Flames fans are met with long lines for bathrooms and concessions and congested concourses. It's severely outdated.

In terms of seating, I am a season ticket holder for section 118 and I have been for years. This section is very small with only 13 rows to a section. Both benches are across the ice on the opposite side so you get great glimpses of the player shifts.
The 100s at the Saddledome are very expensive. By all means, avoid the upper levels especially the 300s; the hike to your seats are just way too steep.
