For anyone who hasn't come across them, it's a relentlessly 1950s style doughnut emporioum with branches mainly in London and one in Brum I think. The USP is making doughnuts on site Willy-Wonker style behind a glass wall. Now normally I wouldn't even think of going somewhere like that, but someone brought a tray of their doughnuts in to college once and they were pretty darn good.
On visiting, it turned out they roast their own beans on site which was a suprise and as you know very unusual, in the UK at least. They had a 3-group rancilio and tamped the PFs (also quite unusual in the UK) and the pour times were reasonable. Although I didn't have a sense of smell at the time, the milk drinks were rich and free from bitterness. It might vary between branches but at the one i went to at least (near New Malden) the attention to detail was impressive.
So if you happen find yourself near one, I'd tentatively say it's worth a try, especially if you are partial to the odd doughnut or eight (Though NOT on a weekend, unless that is you enjoy the company of 200 pre-teens high on sugar ) Happy dunking . . .
