The time to work up an appetite starts now -- DFW Restaurant Week returns for a 19th year on August 15-21. Reservations open Monday, July 18.

See the list of 100-plus participating restaurants here!

The annual charity event offers hungry North Texans an opportunity to dine at more than 125 of the area's most revered restaurants at a discount. Each eatery serves a three-course prix fixe menu for either $35 or $45. Better still, 20 percent of meal proceeds benefit the North Texas Food Bank and Lena Pope, which provides counseling and education services for children.

DFW Restaurant Week Food and Wine Festival

New this year, the week kicks off with the two-day DFW Restaurant Week Food and Wine Festival, which promises "culinary experiences by top restaurants, domestic and international wines, cocktails and more." The event, which takes place at Main Street Garden in Downtown Dallas, runs 5-10 p.m. on Friday, August 12 and Saturday, Aug. 13, and features musical acts Big Bad VooDoo Daddy and Magic! (Tickets are currently on sale and costs $15-$150.)

If you're saving yourself for sit-down dinners, here are a few tips to make the most of Restaurant Week:

Making a reservation

The single most important thing you can do during Restaurant Week is claim a table. Reservations open July 18 to more than 125 local restaurants, and you'll have to note you want the prix fixe menu, as these businesses will still be serving non-Restaurant Week customers. Spots are known to fill up quickly, so the sooner the better.

Choosing a date

Restaurant Week officially runs Aug. 15-21, but select venues also participate in "preview days," which will be Aug. 12-14. Additionally, many will extend Restaurant Week specials until Aug. 28 or Sept. 4. (Differences will be noted when GuideLive posts the list next week on July 18.)

Getting a little extra

Dinners cost $35 or $45 for three courses, depending on where you dine, but you can earn a fourth by shopping at Central Market stores. Spend $25 and request a voucher for a free fourth course at all D-FW locations; those who do so on July 18 will earn double the vouchers.

Many of participating Restaurant Week businesses will also offer lunch specials -- $20 for two courses.
