that lawyer girl?
depends on how well you know each other... if you've only seen each other once but have spoken a bit over the phone/sms/email then i'd go for bird gardens/coffee (or both)
the important thing in a first date is that you dont want her to feel trapped, she should be able to abort whenever she feels like it, this sets her nerves at ease and when she's relaxed she'll be a lot easier to attract. a relaxed smile and a fun, energetic and positive attitude and some kino and you'll have your second date. look for indicators of interest (her leaning in, keeping good eye contact, laughing, touching your arm, winking, teasing you back, punching your arm when you tease her, saying "thats mean" and then laughing etc) a nice game i like to play during coffee is to get a table where you can see the whole coffee shop, have her sitting next to you (at 90 degrees at least, she should have a good view too...) and then talk about the other people in the shop ("he looks like an accountant, she's a broker, he juggles on the side of the highway while wearing rugby shorts and a parka") its fun and interesting. if you think she's into you but you're not sure, take her hand and squeeze it softly. if she squeezes back then its going pretty damn well, player ;-)
if you've seen each other 2-3 times and have had good convo and some kino then movies are good because she would feel comfortable enough to sit for 2 hours with you. romantic comedies are lame. stay away.
an emotionally charged date (like something extreme) is good for a second or third date after you've built that tiny bit of initial attraction. i like go-carting... challenge her to a race, loser buys coffee. or you can take her to gold reef and ride some coasters. abseiling and rafting might be a bit extreme until you've had 3-4 really good dates, and even then she might not be into something that extreme.
