Just the two: https://www.abbeydalebrewery.co.uk/directory/. Can't recall if this was ever any different.
I've not been to the Coach & Horses, as it's a Thornbridge pub. The 43 bus stops close by and it's on the Sheffield side of Dronfield, so I would guess doing it from Sheffield would be better than Chesterfield. Train from Nottingham (or Derby or Chesterfield) to Dronfield every hour, then 43 bus would do too, if you don't like long bus journeys.
Bath Hotel was my local for many years, and in my view Thornbridge have messed it about too much, but if you've not been before, or even if you have, then it's still worth a visit. I've not been to the Francis Newton for three or four years, but it always struck me as a pretty poor pub, but then I never was a great fan of Spoons. The best thing about the Bankers Draft is the back door which leads directly to the Dove and Rainbow. I would have thought The Benjamin Huntsman (JD Wetherspoon) was the best of the town centre Spoons.
