dinner date

I will have a dinner party with my all classmates.
We will go out to eat dinner with our two teachers next Tuesday.
We can’t wait for that day after teachers ask us to order the dish.
I think it is a high-level restaurant because the prices are not low there.
For the date, I have to change my holiday. I have to thank my colleague.
I think he is a nice person, I mean only on this thing. Haha…
