Not sure this is the right place to post this

So I've just taken early release from my job and will have around £30k in my pocket as a thank you. So I'm thinking of investing and starting up a business but not sure what yet. Currently I'm looking at a bar in my local town which is up for £55k pa and I know it has a lot of potential. Fully refurbed just under a year ago but I known nothing about the pub business really.

Does anyone have any advice on this industry? Maybe someone with some past experience of running a bar? I do know the old owner of the bar before the refurb but he's on holiday at the moment so I can't speak to him but he did really well and made next to no effort in running it (Used to close at 7pm on Mondays and Tuesdays even if there were customers - and even then it would be sometimes that he did this so no consitency).
