If you want to make a good impression, then take her somewhere nice for dinner. If it were me, then I'd go to Mitchell's steakhouse in Polaris. You like this girl, right? Then do it right, playa.
Then, after dinner, you might go somewhere fun, like Dave and Busters or whatever. There's Magic Mountain up in Polaris too. You said you think she'd be into something like that, so either of those places might be winners. Pairing the fun stuff with the nice dinner can be a winning combo: let her know with the dinner that you're serious, you're a baller, and she's worth the coin, and then let her know with the Magic Mountain stuff that you aren't boring or just into stuffy restaurants and can have fun.
