Interesting or unique first date conversation ideas?

If you two hit if off, no tips are needed.
The main tip is to be INTERESTED in who they are as a person and how they feel about things. Don't make it feel like a job interview though.

The point of a first date is to try to find some common interest you share. So talk about your work, your hobbies, your interests until you find something you both like...then talk about that.
