Just over a decade old, the former Centre Molson is the home to the Montreal Canadiennes. I love this place. It's hard to judge an arena since they are fairly generic but this one has appeal. The frosty Molsons may help.
I have had the pleasure of seeing three concerts here. 2 Depeche Mode shows and Our Lady Peace with Finger Eleven. The acoustics are great and the staff/security was relatively friendly.
