Bosun / Ian,
I think you have to draw a distinction between the age groups.
There is a relatively vibrant social scene for over 50's, couple etc... in terms of going out for meals, churchy stuff, darts, etc.
But for singles and younger folk Llandudno and the local area is lacking in a vibrant social scene outside the summer months.
I've also just heard that the open mic night is coming to an end imminently, not enough interested apparently. That was news to me, it always looked busy to me.
However, having said all that, I am over 50 , and I do enjoy life in this area very much.... but when my daughter and her chap come visiting, they are a tad bored.
