I'm old by now, but I started dating when I was 14 so I thinkI know a thing or two about dating.
Do some homework on the restaurants and the movie
to ensure that the lady would not feel offensive.
You may even want to visit the restaurant ahead and
familiar with the menu and price, yeah, you might get to
know the Maitre D or hostess, vice versa so you may pretend
to be a frequent guest. For the movie, you may rent a DVD
and view the movie first. Sometime it would be distracting if
an attractive date sitting besides you.
Then there would be quite a bit to talk about the movie at the
dinner/drink and afterward.
And for drink, know your limit and do not embarrass yourself,
knowledge about the beverage will add your score too.
Just be prepared, relax and have a good time.
