She’s got a right to try, but it sure sounds like a field that, well, tends to suck one’s blood. Who’s ever gotten filthy rich from restaurants? You’d have to love doing it. Of course a good place can be very very memorable, but others’ memories don’t pay your bills, alas.
Maybe “Quit if possible” is the best advice for her. Go into a different kind of business.
