Even the normally sanguine Kimberly Cacioppo, who works as a part-time hostess at P.F. Chang's China Bistro, gets a little perkier talking about the handsome men who whirl around this bustling dining room in crisp white shirts, tight pants and white aprons. "They're darling, darling, darling," she coos, adding that, although she has a distinct visual appreciation of her coworkers, she doesn't flirt with them. "I don't date men I work with," she says. But plenty of customers would like to date her colleagues. From her vantage point at the front desk, Cacioppo gets lots of wishful comments. It's not uncommon for regulars to insist on being seated in the section of dark-eyed, bearded Bill Simpson, or to place an order with tall, blue-eyed "to-go guy" Billy Ash. Even the busboys are swarthy and hunky. "Total porno material," swoons one customer. "We do get a lot of comments about the attractiveness of our servers," says Mark Kirke, the restaurant's operating partner. "They tell me, 'Where do you find these people?' And the answer is, I guess, that they come in and apply."
