El Fenix Mexican Restaurant has been pulling out all the stops for its 100th anniversary and now the originator of Tex-Mex cuisine is sending one lucky winner and a guest to Mexico.

To say ‘thank you’ to its loyal customers for helping El Fenix become the longest-running Mexican restaurant chain in the U.S., the Dallas restaurant is giving away a four-night Funjet VacationsÒ getaway for two to either Cancun or Riviera Maya (winners choice) with all-inclusive accommodations at a RIU Hotels and Resorts property. Round trip transportation between the airport and hotel is also included.

“We’ve been celebrating our 100th anniversary all year and we’re excited to have the opportunity to add this amazing giveaway,” says Brian Livingston, president and COO of Firebird Restaurant Group LLC, which bought El Fenix from the Martinez family in 2008. “El Fenix wouldn’t be where it is today without the ongoing support of the Dallas-Fort Worth community, so we can’t wait to send one of our loyal fans and their guest on the ultimate beach vacation!”

Enter to win this trip of a lifetime by joining the El Fenix e-club at ElFenix.com/Enter between Aug. 13 and Sept. 13.

In addition to the beach giveaway, El Fenix is hosting an epic 100th anniversary party on Thursday, Sept. 13, at the flagship location at 1601 McKinney Ave. in downtown Dallas. Partygoers will get to experience food specials, live music and more. Throughout the day, El Fenix’s downtown location will be offering $1 cheese enchilada plates from open to close. Also, the first 750 dine-in customers ages 13 and older will receive a free commemorative El Fenix Centennial Coca-Cola bottle.

There are 22 El Fenix restaurants located throughout North Texas, and at WinStar World Casino & Resort.
