Hi Puzzling SE at the moment I am at a romantic night out in a fancy restaurant. Tonight the owner, Luigi, who is also a riddle fanatic has decided to put a little riddle on the menu. It was stated that whoever could solve it would get whatever free 3 course meal and bottle of wine for himself/herself and the partner. I really want to impress my wife tonight and I have roughly an hour here to solve the riddle before we finish our meals and pay the bills. Can you help?
Riddle:
"VVV!", said a M called C when C L on a C with a flag with a X that was not D.
Who is it?
