Llandudno must be up there with best sea fronts.
This town was created by one family in victorian times, and
there were limits on the heights of buildings (no building could be higher than the width of the road for example)
All the buildings (hotels and shops) were leased so the lease owners still have the right to control any external painting, extensions, signage and so on.
So, for example, every sea front hotel has to ask permission to repaint the front of their hotel, and it can only be from a designated list of "soft" colours. After it has been repainted they come round and check it has been done with the right colour.
This has preserved the town and it still has some lovely Victorian buidings and has never had the awful seafront shops and arcades many others towns have got.
Here are a few of pictures of the sea front:
