Thanks! Having read up, I'm specifically after UK raised "rose" veal, which I understand is supposed to be the good, hipster food choice, as opposed to the white veal that was bad in the 90s*.
I got some in one of the small supermarkets on Clerkenwell Road, can't for the life of me remember where exactly but I'm sure if you go to a biggish M&S or Waitrose you should find some.
Selfridges certainly have veal, but it ain't gonna be cheap!
