Dating is kind of like bidding for something on eBay. As the auction gets closer and closer to ending, you get more and more nervous, wondering if you'll win or lose. So you keep constant watch in the last few minutes, increasing your bid $1.00 here, $1.00 there till it's over. But there's no need to do that if you simply decide, from the get go, how much this thing is worth to you, and bid that at the beginning. If the bid goes over, then it's over, cause bidding any more is cheating yourself.
The same goes with dating. If you want your date to blossom into a long term relationship, then you should feel free to (I normally hate this term, but here it is) be yourself. If you hate fancy restaurants, then don't go to one. If your favorite topic of conversation is the social significance of Japanese manga on adolescents, then don't shy away from it. I'm not saying to be a selfish prick and reject anyone who doesn't like exactly what you like, but the further you travel from your 'comfort zone' of behavior to try and impress a girl, the more you cheat yourself in the long run.
In short, any date either will or will not succeed at the end of the night. So enjoy yourself and have fun on it. It's not an interview, after all.
