I have had a trawl round on the Internet, and there is a suitable restaurant/pub called the Stable Gate (been there and can recommend), right near the M60 motorway at Denton, which is also convenient for Bags and Sewsilver, being nearer to Derbyshire. It's the same distance for those of us who joined the M60 in the south, you just go in the other direction. It's easy to get there from the M56 and M62 east, but a longer journey for those Gransnetters coming from Liverpool or Blackpool areas, so more suggestions are welcome.
Preferred dates seem to be those when Bags is coming this way, on 15, 16 or 17 February.
