On a tip from a Sydneysider friend, we went with the "Coat of Arms" pizza. Take out a 50 cent AUD coin and check out that Australian coast of arms on the reverse, and you'll find the magnificent profiles of a kangaroo and emu flanking a shield. It's the meat of both these animals you'll then find on the "Coat of Arms" pizza, hence the name.
While you're waiting for that pie, have a look around. The Australian Heritage Hotel completely lives up to its name, being the oldest continuously licensed pub in the City of Sydney and included on numerous historic architecture registries.
Prices aren't cheap, with specialty pizzas starting from $16.50 AUD (the Coat of Arms is $19.90), but consider the factors at work here: historic location convenient to major tourist sites, local and exotic ingredients, awesome beer selection to wash it all down. Not to mention that it's an easy story with which to delight everybody back home, when they ask what you got up to Down Under!
