It certainly seems silly to offer dining and live music at the same time in such a venue. The Railway is not a place that would even register in my radar if I was trying to think of a place to go for an evening meal, at the weekend at least.
I get the impression the management is trying to cover too many angles there. I'm sure it brings a healthy profit but they host so many private functions during the Spring & Summer, it often feels as if every other weekend the pub is closed for a wedding or birthday party. Last year a friend and I found the pub closed for private functions on three occasions on a Saturday in a short period of time, after which we decided to meet at a different pub.
