Where to slum it on my birthday

Ive eaten at most of Auckland's high-end restaurants a few times but I fancy slumming it for my birthday. What's your guilty, low-brow place to get stuffed?

I fancy a few drinks, then a mid afternoon feed, followed by a little irresponsible shenanigans.

I dont mind traveling BUT I do live in whangaparaoa so bonus point for CBD or north of the bridge.
