In an effort to publicize its newly launched Instant Deals offering, LivingSocial will point users to a slew of $1 lunch deals in Washington, D.C., on Friday.

The deals will be available to anyone in the city who logs in to the Instant Deals feature on LivingSocial's mobile app. Using GPS, the app will pull up a list of such deals within a half-mile radius of the user. The deals will be available between 11 a.m. and 2 p.m.

LivingSocial didn't give the full list of restaurants taking part in the deal, but two are Sticky Rice and California Tortilla in Chinatown.

LivingSocial launched Instant Deals on March 7, which competes with offerings from AT&T and Facebook, among others. The D.C.-based LivingSocial competes fiercely with Groupon, the leader in the group-buying category. In fact, LivingSocial claims it will overtake Groupon in market share in January 2012.
