The karting thing is a lot of fun. I've actually taken a couple of dates there, one was a first date, one wasn't, both times were a complete blast. They were both really small too, I don't think it was that big of a deal.
I had it planned for having lunch after, makes it more of a casual thing, easier to dress for something that will fit both. We hit Bahama Breeze the last time, close to Sykart and good food. If you want to take her out to a fancy dinner she might look a little silly driving a kart in a skirt and heels, so keep that in mind.
Or another option is to just wait until tomorrow and bring her to breakfast at XXX. We'll all be nice.... right guys?
I may actually bring along a friend tomorrow, but not a date, I'd have to be pretty sure that she wouldn't bolt before I brought her around a bunch of car/internet geeks.
Benihana is a lot of fun, if you don't mind spending that much on a first date. Just be sure to get reservations.
There are always those ultimate pickup lines too... "Hey baby, does this rag smell like cloroform?" or "Nice shoes, wanna f**k?"
