I thought I'd paste the very last paragraph from the interview you posted. Links tend to disappear over time and it answers the original poster's question.
When not acting, Wheeler-Nicholas is often teaching other actors, out enjoying music, or singing. She has quietly gotten serious about performing mostly jazz and hopes to record soon. She'd also like to be able to have a sustained film career from Austin. "There should be enough production here, but there isn't as of today," she says, expressing dismay at the Texas Legislature's likely cuts to filming incentives. "I haven't heard a rational argument against [incentives] yet."

I've found a brief interview with her posted on www.austin308.com from January 2008. After Fletch, she says she was offered lots of parts she didn't like and turned them down. Her current interests are singing and she's pursuing a singing career in Austin TX.
Before reading that article, I'd have expected to find her on Broadway between films but there's no mention of that. Or being a hostess in a restuarant for that matter. An awful lot of space seems to be devoted to her hair! (Not that there's anything wrong with that.)

i'm pretty sure i read it in an issue of Empire, a uk movie magazine, when he was promoting the 3rd bourne. and it was the interviewer asking him about fame and making it and stuff and damon said that when he was younger when he watched a film he thought all the actors were rich and had made it but when he saw her at the club he knew it was just a facade.

It could be she's helping out a friend or something.
Considering she was 39 years old in 1999 it could be she was taking a break from acting. That's usually the age when actresses who pretty much relied on their looks and hasn't established themselves in Hollywood start contemplating what to do with the rest of her life. The ones serious about acting continue while the ones who only cares about stardom disappear and are never heard from again. I'm glad she continued acting I like her a lot.
Badder than old King Kong, Meaner than a Junkyard dog

I don't remember at all - it was probably summer 1999 and no, she didn't own it, as I understand it. But it was definitely her. All I could remember at the time was that she was in Fletch.

Maybe she owned the place?? What restaurant was it? After lusting over her for 22 years it would be cool to meet her.

No - she hostessed at a restaurant I went to years ago in Southampton.

Probably someone with similar looks.

matt damon said he went to a club a was shocked to find she was the hostess there!!
