Moe's Southwest Grill has launched a mobile coupon campaign to whet the appetites of potential customers - and introduce them to some interesting temporary menu additions. The Atlanta-based chain's latest limited-time offers are the Phil E. burrito and quesadilla.

Both the burrito and quesadilla spice up the classic Philly Cheesesteak with steak, peppers, onions, mushrooms, shredded cheese and Moe's famous queso.

Since they're only available until May 31, Moe's launched its first mobile campaign to raise awareness. Visitors to any of its 400 locations nationwide can text "MOES" to 46786 to get a mobile coupon for $2 off their next Phil E. purchase.

The chain started its mobile efforts in January when it began working with Fishbowl to build a VIP mobile database, which now has nearly 5,000 opt-in consumers. It's working with Opt It on the SMS campaign.
