The 'Roo provides the best motorbike leather and excellent steaks.
After the east european / French horse meat scandal I'd rather have 'Roo than processed burgers.
Mustard is appreciated by those who...well appreciate it. If anyone doesn't and some obviously have an aversion then don't use it.
All the more for me
Roo is quite nice, really.
and what's wrong with eating a bit of horse meat?
