Thanks to all those who recommended it. We've just watched the first two series. Really good. Roll on season Three!
I also tried it after reading the previous recommendation. Love it so thanks to whoever it was! I'm just behind you @churtonred - final two episodes of season 2 to go.
Also on Amazon is a programme called Nothing about an eccentric food critic living in Buenos Aires. We've only watched a few episodes so far but it's pretty good and different.
