Waggoners is still a goner, I'm afraid, but it's still worth stopping and having half a day wandering on the Mosses - about as alien a landscape as you'll find in the lowland midlands, though the horseflies will be out later in the year.
In Llangollen and for beer, seek out the Ponsonby Arms on the road towards Trevor. Lots of beer and an excellent jukebox. Same people as have the Sun on the A5, which is a unique pub. I love it (the Sun), but it isn't to everyone's taste. Jazz on a Thursday, more....exciting bands on some weekends.
If you want a more sedate evening, then Gales winebar or the Cornmill. Both are excellent eateries (though Gales was once quite contraversial back in the days of Dry days in Wales).
Really not impressed by the Lion Quays - trying a bit too hard and not really getting there. Oddly enough the old golf club at Chirk marina is now a splendid little bar with good food and real ales. Not sure it's getting the footfall it deserves, yet.
Also worth stopping at the Sun Trevor. pub is ok, but if you can face the uphill haul, the walk along the Panorama underneath the limestone outcrops and the old quarry/tramway is fantastic, or you can do it via Dinas Bran from the basin. Eitherway well worth burning the calories for.
