A Brunswick East burger restaurant lacks its yak after the mounted, decorative head was stolen from the venue by single-minded thieves.
The synthetic yak, nicknamed Bryan Yakety, was the only item stolen in the break-in at The B.east restaurant on Lygon Street.
Police believe the thief broke into the venue sometime between 10am on July 8 and 10.30am on July 9 and made off with the yak, which had been mounted on a wall in the lounge area.
B.east owner Maz Salt said he was distressed to discover the synthetic bovine had been stolen.
“We are very fond of Yakety and I was most upset to discover that he has disappeared and I urge anyone who knows what happened to him to come forward”, Mr Salt said.
The restaurant has posted a mock Wanted poster for the yak on its Facebook page and is offering a reward for its safe return.
"We can confirm he is approachable, very friendly and loves beer," the post writes. The yak is described as about a metre in size and brown in colour. It has no body.
One user joked the yak might have left at its own accord. "(It) must be torture watching hipsters munch on your cousins," they wrote.
The burger bar opened recently and had previously housed a Turkish restaurant, also owned by Mr Salt, which closed in March.
Police are appealing for anyone with information on the theft to contact Crime Stoppers on 1800 333 000 or visit their website at crimestoppers.com.au.
