I have.

There's nothing to worry about. Be yourself, take her out and do things your way. You don't need to take the taxi to go to some fancy restaurant and then watch a musical. You can cook a nice dinner and invite her over and watch some vintage movies on DVD, and maybe do some things afterwards.

Girls dig personality. One thing that might fascinate her is how much fun you can have without spending the amount of money she's been spending.

The only thing you should keep in mind is that, you shouldn't act like a bum and embarass her in front of her "rich friends". Like ordering grill-cheese sandwich when everyone is having lobster. You don't need to go with the lobster, you've much better of with a mid-price speciality dish that start everyone talking about it.
