We had/have beef mince pie ,mash potato and liquor shops in every street market in London ...it was a cheap meal for the poor and market workers.... It's just the same now but very expensive......they use to have saw dust on the floors ......now they are filled with city toffs in their fancy cloths sluming it with the Peasants :(
There I one shop that my parents use to take us kids to when we were little......I still go there now when I'm in the east end of London..... The same people run it and it's where the East London gangsters the Kray brothers use to eat.....
