LOL, I forgot to mention while I was next to that table of scary patrons I found myself sliding my purse between my feet!!! Now that's really bad when a person feels that unsafe. Try to relax, enjoy a meal while holding a purse with your feet and glancing around nervously.
They have clubs in NYC that cater to that clientel. They'll go through cases of high end champagne every night.
As for your purse, you'd be surprised the types of restaurants where coats and purses are stolen...
