I will go lunch

I was invited my friend for lunch. So I decided to go with her. She is one older than me. I and her have same part time job. We are good friend because our age is difficult. I will go lunch at September 10. We are going to have Syabusyabu. Syabusyabu is easy dish that we are boiled slice meat in to hot water. So we put them in souse.
