BEST happy hour auckland central???

Where's the best happy hour at the coolest bar in town? Looking for the best between the two. Looking for CBD / viaduct / K road / ponsonby ... somewhere central. I'm a postgrad student who LARPS as a city worker, so preferably not filled with 18 year olds nor filled with geriatric boomers. But I can get down with intergenerational drinking if the place is cool enough. Thanks in advance**!**
