Was in St Pauls (London) a while ago and came across this butchers. Probably a bit more expensive then my local but can't get beef ribs for love nor money around me:
Post Rub
Cooked them together through the night (about 14ish hours at 210-250F)
Looks great, the advantage of Barbecoa is that Adam Perry Lang setup their meat supply. He visited loads of places and goes back regularly to make sure the quality doesnt dip, but, London prices............
