The kind of art I'm used to looking at is typically made in the foam on top of my latte. That should give you an idea on how much I frequent art galleries. It's fun every now and again, but often, it takes an event to get me into one... at which point I find myself perusing the walls with my eyes as I mingle my way through a party. Which is exactly what I did on Monday night.
In terms of an event space, the AGC has a lovely layout. Great mood and setting, light coloured walls, four different levels. The top floor being my favourite, though it got a wee bit warm up there... the only thing of note if you're planning an event here is that the food seemed to flow from the upstairs down. If you're using the entire space, you may want to find a way to ensure a good portion of your food also trickles down to the lower levels.
