That might be the Poachers Pocket, but this is before Chirk Marina as you head towards Llangollen.
I've been told by several people who have worked at the Lion Quays that a lot of the food is bought in as prepared catering packs and simply microwaved.
At Maestermyn there's the Narrowboat, family friendly [noisy!] and the food is OK but I had a steak and kidney pie there that looked microwaved but tasted fine. The Jack Mytton is worth a visit and just a mile further than Maestermyn.
If you don't mind a hike or short taxi ride then Ye Olde Boote in Whittington is excellent, if you can't get in there then The White Lion 100 yards away is supposed to be good too.

Edit to add: The castle at Whittington has had a lot of work done on it in 2007 and is now well worth a visit if you like history, there's some well drawn displays showing how the castle has evolved over the years, and a tea room too. The castle is right across the road from Ye Olde Boote Inn and next door to The White Lion, there's a chip shop around the corner and a kebab/burger place opposite that.
