Secret menus at restaurants and fast food joints are no longer much of secret nowadays thanks to the blogosphere, since many blogs and websites frequently post lists of menu items upon each discovery.

But now, a new article from The U.S. News and World Report alleges secret menu items are becoming a trend and even a marketing tactic to drive sales and news customers.

According to Jonathan Marek, senior vice president of Applied Predictive Technologies, who was the lead source for the expose, nearly every restaurant has a secret menu. Marek said many food blogs have catapulted the hidden items into fame, which result in happy customers and thriving business.

"Many of these food blogs have pushed this trend quite a bit, where you've now got people going through the drive-thrus and thinking of creative ways to put different sandwiches together,” he said.

Marek said the movement to include secret menu items was led by In-N-Out Burger, which infamously began the tactic over 20 years ago. The West Coast fast food chain boasts on its website:

“Urban myth or just plain excellent customer service? Ok, you’ve heard the rumors, wondered what was on it, maybe even felt a little left out of the loop. But in reality, we don’t have any secrets at all. It’s just the way some of our customers like their burgers prepared, and we’re all about making our customers happy. So here are some of the most popular items on our not-so-secret menu.”

Now, Marek says, other restaurant chains have followed suit over the past five years, many items having been requested or thought up by loyal customers and are not intended to be hush-hush.

"We don't really think of our secret menu as secret," Scott Davis, executive vice president and chief concept officer for Panera Bread, said of the menu which debuted in January. "We think of it as hidden. We want people to talk about it."
