The Boar Hat was established after the Seven Deadly Sins were branded as traitors of Liones. Meliodas founded the bar in order to collect information about the whereabouts of his fellow comrades and information about many of the Holy Knights. Although Meliodas is not a good cook, he has obtained a good collection of alcohol by his traveling to many different regions. Elizabeth is later hired as a waitress in Boar Hat after she finds Meliodas and decides to join him in finding the other members of the Seven Deadly Sins. It was revealed that Meliodas sold his Sacred Treasure, Lostvayne, to get the money to buy the Boar Hat.
After Meliodas' death, the bar is run by Elizabeth for about a month until his resurrection. However, Hawk Mama, carrying the bar, is attacked by Derieri of the Ten Commandments and the bar is destroyed by the 52nd hit of her combo.
The Boar Hat was rebuilt on Hawk Mama's back and was designed that each of The Seven Deadly Sins had their own room or space. It now appears as the shape of a tankard. The Seven Deadly Sins have their reunion party there and start to discuss how to finish off the Ten Commandments.
