The difference is about 9 miles really , about 15 minutes driving.
Both have their advantages, coffee and food is good in both places.
The Owain Glyndŵr Senedd-dŷ is not open until Easter, so the display boards are not up. Otherwise I could have arranged a look round and maybe some harp music! Maybe in the summer......
On the other hand, perhaps we could show you the plans we have for the place (drawn up by the same architects as designed the new Cletwr building).
