I eat Cenovis (available from my Coop) when my Vegemite supply runs dry. Not exactly the same but pretty close...you'll either love it or you'll hate it
English beef can be very good indeed. Both the Ginger Pig in London and Northfield Farm supply top quality meat.
I'm sure Swiss beef can be very good, but I don't think you can get it in Coop.
Beef needs a bit of marbling . . . depending on how you cook it this can improve both taste and texture. Swiss supermarkets favour meat that is extremely lean.
I'm led to believe that much better meat and the possibility to have it butchered as you'd like is available direct from some farms here.
