I can't be bothered to comment onthe ethics sorry but the bread - what is it with London burger bars and the bread??! You know I have an issue with it and I know you are quite particular too but we only have one request really - use a proper burger bun! Hawksmoor have taken it to the next level with the brioche obviously but it is still in the sweet and soft style. A floury bun is not a desirable casing for a burger. I guess its all down to personal taste but then, a burger bun is a burger bun for a reason!
