My hobby is Aikido, it's a martial art. I don't eat right or go to the gym to be healthy, look good, or live longer. I do it to be better at aikido. When I can't do that I do all those other normal things like read books, go to concerts, watch weird movies (MST3K style movies), etc.
I have an eclectic taste in music. I listened to bluegrass covers of Modest Mouse and Led Zeppelin today then switch over to surf rock. I've been collecting indie rock t-shirts from the concerts that I go to recently, if the band is any good live. I'm against music that mentions trucks or "poppin caps" in general.

Movies are right out. Dinner too probably. The most important thing to do on a first date is to build a level of trust and comfort between the two people. I find that I can do this best when you're in a place where it's easy to talk and there's a good escape plan. If I find out you're psycho during appetizers I'm stuck for another hour or more. If I find out you're psycho after I just get my tea, my tongue gets burned and I'm out in 15 minutes.
