If your 2012 New Year resolutions include losing weight, eating healthier and spending less you may want to consider putting those resolutions on hold for a week.

This is the time of year when food lovers from coast to coast rejoice over two basic words, “Restaurant Week.” The concept is simple. Cities promote one week (or more) in January or February to lure foodies or anyone who loves to eat into local restaurants by offering reduced price-fixed menus for lunch and dinner. Diners get to experience a memorable meal and restaurants get a big boost in return.

The original Restaurant Week was born 20 years ago in New York City, “as a one time culinary event” to coincide with the Democratic National Convention in 1992. What started out with 95 restaurants offering three course meals for the bargain price of $19.92 has grown into a three week (20 days in honor of the 20th anniversary) dining experience including more than 300 restaurants. NYC’s Restaurant Week runs through February 10th (Monday-Friday only) with prix-fixe lunches for $24.07 and dinners, $35.00, featuring more than two dozen cuisines from A to Z.

Today more than 50 U.S. cities are cashing in on the Restaurant Week philosophy, giving diners the opportunity to discover new restaurants (and old favorites) for a real value. Check out how four cities are turning RW success into big bucks.

Since then the event has grown significantly, expanding into twice a year, summer and winter Participating restaurants only offer three course dinners for $30.

The most recent Restaurant Week, July 2011, included 92 restaurants and 90,000 dinners sold, generating $4.2 million.

The Los Angeles Convention and Visitors Bureau. “The program has not only showcased the City’s rich range of restaurants, it has also boosted Los Angeles’ economic engine.”
