VIP MARY
Phone: 714-262-4500
No reviews
Woman with Russian accent answers.  Sounds older than 25 over the phone.  Rate is 400.  She assures me the pictures are real, but when I ask if we can meet in the lobby she says she is out-of-town at the moment, and I should call back in an hour. Did not call back.
