It was pretty cool indeed and worth a visit (plus I got a legit pie up in the town after, also worth the visit). I didn't know about the bread advert to be honest, I know I want to see it. If you get there, take the time to go to the abbey/museum too, it was worth the entry fee.
Cheddar Gorge, yeah we loved it there. Didn't do the cliff walk though so will have to go back. Interestingly, they found the Cheddar Man there (oldest intact skeleton ever found - 9,000 years old - which you probably know anyway)...when we were in London at the Museum of Natural History we saw the actual skull of the fellow which was a nice connection. The caves were amazing there under the mountain though...the reflections in the water sitting as still as glass in the pools and all. Incredible...as was the pie I had at the shop down the road that day. (Seeing the pie theme?)
We'll have some folks to visit when we're there next. I'll bring gifts for one and all.
Get your ass to Shaftsbury!
