To quote; Sit around and have deep thoughts about being unemployed. but it's also a good thing too have for barman chatter.
Getting licencing is easy, but it's the red tape once you're running that'll drive you nuts. Fire safety, disabled access etc can send a sane man to his grave.
Best way around it's to apply to open a members bar, that way you can circumnavigate half the crap, ban the riff-raff, and have longer opening hours.
Best of luck to you though.
