IJL's Web site boasts more than 30,000 current clients worldwide, and the California-based company reported $35 million in sales for the 2005 fiscal year, with a one-year-sales growth of 16.7 percent, according to Hoover's, an online business information research site.
The company was founded in 1992 by Andrea McGinty, after her fiance jilted her weeks before the wedding, Hoover's reports. McGinty went on to marry Dolan. They sold the business last year to a New York private equity firm Riverside Co.
Balestriere said that a three-month investigation by his law firm turned up "dozens and dozens" of disgruntled former clients of It's Just Lunch, and that he and his colleagues spoke with a number of former IJL employees. He did not make the former employees available.
One affluent former client of IJL contacted independently by ABC News said there didn't seem to be much "rhyme or reason" to the matches she was set up with.
"I was slightly disappointed, but I didn't really have very high expectations," she said. "I wouldn't have believed them if they had told me they were setting me up with some amazing Prince Charming type." The woman said that, in general, she'd had a good experience.
"It gets you out of the house," she said.
