Nemesis ..... it's not just you, it's every discerning visitor to Llandudno, and like you, they will move to the next food outlet, or worse another town for their next outing........apart from the pavements, I also notice the fabric of the upper buildings in Mostyn St. leave a lot to be desired, gutters etc. its the main street, its the one, most will see.
Last year, walking past the smaller hotels, (top end north shore) I said to my companions, "you would think these owners would pay more attention to their pavements" I was overheard by the owner, sitting in his well kept garden, who informed me, in no uncertain terms "that he had bleached and pressure washed said pavement and later, had been advised by the council not to do it again " an HS issue? maybe the bleach, maybe the overspray, but, its a shame when someone tries . looks like its down to the council for heavy cleaning.....ah well.
