Once you have your finnance, and premises, you need to apply for a licence to sell alcohol - contact your local Council. Subject to the granting of your licence, you need to arrange for fitting and decorating, stock, staff, etc. Don't be fooled by sitting in your local watching mine host chatting over the bar to customers - it is really hard work, long hours, and you need to know what you are doing before you embark on a venture like this. If you still fancy the idea, get a part-time job in a bar to see if the life suits you, before you take the plunge with a risky business venture.
