If you feel nervous about making the first call or writing the first email, just keep it brief. The date is where you get to know someone, and the email is just to arrange the date. Here's an example of a short email:
"Hi ______,
It was nice meeting you last Thursday. It is amazing how many things we have in common. I am interested to hear what you thought of the new _____ album. Are you available to have dinner on Wednesday or Thursday? I have a good place in mind.
Have a good day,
________"
