If you ever need to kick your appetite into gear, feasting your eyes on Pie Town's social media feeds is a surefire tactic. Or, you could tuck into its enormous array of pies — including on the absolute best day for it.

Yes, there's a day for everything, but calling March 14 'Pi Day' is immensely fitting. And if you can still recite pi well beyond 3.14 (putting your school maths classes to good use), Brisbane's home of pie wizardry will reward you for it. On Sunday, when the date rolls around, it's handing out $3.14 slices and coffees as part of a pi memory contest.

There is a catch: to get the deal, you need to recite pi to more places than the person before you in line. So, arriving at 10am when things kick off is definitely recommended.

If you're just keen on pie without having to remember pi, there'll also be a few special flavours on the menu to mark the occasion — including an Elvis pie that's made with peanut butter, bananas and bacon.
