Niko and his date should have a good time from the get-go, so bring your girl to a local eatery or other place of amusement and have an awesome time.
Usually, this will involve a burger at Burger Shot, or perhaps some beers and darts at a local Irish pub. Regardless of what it is, try to diversify each time you go out with a girl, and be especially mindful to listen to their feedback as you walk around and drive around at all times.
Usually, from the point of cellular contact, you're going to have an in-game hour to get to your date before she gets miffed for standing her up.
The date can still go on to a certain point even if you're late, but it's definitely not the way you want to get things started.
