The actor, who played George Costanza in the hit show, discovered a drinking den in Melbourne called George's Bar had launched on New Year's Eve (31Dec15), offering Costanza-themed cocktails and snacks.

The venue's co-owner Dave Barrett admits his love of Seinfeld was the driving factor behind the establishment, and when Jason found out about the quirky venue he immediately spread the word.

In a post on his account, the actor writes, "That's right - I may not have an Emmy, but I got me a bar in Melbourne, Australia. G'day, mates."
