The massive egg, sourced from a nearby farm, weighs up to 1.3kg and is served sunny side up.
The mighty meal will set you back US$75, or NZ$109 — but it could probably feed a family of four, to be honest.
The breakfast's popularity has surged since a video of the ostrich egg being cooked and served was shared on Facebook, where it has racked up more than 41 million views.
And in case you're wondering, Provisional Kitchen sounds like a winner — it's got four and a half out of five stars on TripAdvisor.
And plenty of visitors have been won over by the ostrich egg.
"It's colossal!" one TripAdvisor reviewer said. "Easily shareable with 8 people. Served with bacon, potatoes, sausage on the same humungous plate, this will be the centrepiece of your brunch! Definitely enjoy and make reservations in advance!"
