Restaurant Week, usually in late August every year, has grown up: It now includes almost 100 restaurants, from casual family to formal dining. During Restaurant Week you can make a reservation at any of the featured venues and enjoy a prix fixe three-course meal at $30 a person. For many of the more expensive places, this is a very economical way to try out a new spot. All you have to do is look at the list on KRLD.com, call the place and make a rez. In recent years, the event has generated contributions of $35,000 to $45,000 for the North Texas Food Bank and the Lena Pope Home. You get good food, and good causes get some money. Good deal all around.
