I've ridden through it on a couple of occasions, including once on a tour organised by JBB otp and in the company of a few other forumites, but only on the official cycleroute, as far as I know. So can't really say. TBH I'd expect any cafe in a place like that to be overpriced, crowded and not amazingly good, so I'd be inclined to hold out to the next town or village.

Totally OT but the last time I visited Longleat for the animals was way back in about 1994. A friend of friends drove us there in order to flex his swanky shiny new BMW. There are signs before the monkey enclosure warning you they can cause damage to vehicles. He decided to risk it (or we persuaded him, I can't remember) but no one expected quite this sort of damage: An inquisitive female monkey jumped onto the windscreen to gawp at the lesser apes behind the glass hedge. A male monkey jumped in behind her because he'd been watching Discovery Channel. Maggie Monkey wasn't in the mood for being a star of spectator sports and hopped away, but not quite fast enough, because Mark Monkey left a white splodge on the shiny new windscreen...
