My favourite restaurant is the Thai Corner Cafe on St Paul's Road. We go there all the time. I shouldn't really mention it - I don't want it to be chock-a-block.
I wouldn't treat a romantic scene any differently than any other scene. I would really say the biggest preparation was chewing gum and breath mints! For a kissing scene, it's all about the breath mints!
Much education today is monumentally ineffective. All too often we are giving young people cut flowers when we should be teaching them to grow their own plants.
