Heres my idea for it :

You make a permant building on Main for it.
The "Pub" or so is ran by whatever kingdom wins the "Pub Event" for that (2 week or so) time period. The event could be something simple like cards or so. Or you could get more RP style and have an RP event for it. But every (2 weeks or so) there is an event and the winning kingdom retains the Pub on the main island.
You can sell booze and drinks there. But your kingdom must supply it (buy it in shops or make it). You can also choose the price for it though. Whatever money you make goes into your Kingdom Chest though.
Also only people with a kingdom guild tag on can enter the bar. If you dont have the tag on you cant enter. Simple as that.

I think I covered most of my idea.....Might have left a fews things out but I cant think of them now....
