This could develop into a professional service. If your format included an interview with the owner/manager you could offer 'showcase service' for a fee. You could find out about the history of the pub and allow the owners to promote events, menus and give an appraisal of the location, crowd, food and general atmosphere of the pub.
It's more like a presentation. So far, I loved all the pubs I've been too. Also, I am documenting as many pubs and bars in Bham as I can in case they disappear like so many had throughout the years. My favourite pub so far is the Prince of Wales (Moseley)
