Appealing to your demographic

I had the opportunity to pop into the Nags Head in Reading last Friday afternoon for a cheeky pint while waiting for a train and was musing about how that particular pub is so successful when many around it are closing. I think the answer is plain to see, do one thing and do it really well. The "Nags" is a beer pub, it caters for people who are interested in beer of all stripes, it has around 30 on at any one time to choose from and frequently has the most sought after breweries on tap. The proof of the pudding for me was provided in the gent's toilets (see picture above) what pub do you know that publishes a list of beers that it has in it's cellar above the urinal in the loo! Now that's attention to detail and ultimately appealing to your demographic!
