If you're looking for a cheap eat, you've still got an hour to spare. But buyer beware: you might have to jump through a few hoops to get your nearly-free lunch. The dollar deal is only available through the company's iPhone or Android app, only in Washington, D.C., and only if you're within a half-mile striking distance of one of the participating restaurants. Oh yeah, and you have to chow down
during lunchtime, between 11 a.m. and 2 p.m. No rainchecks on this one.This deal is only available in the District, and today only. But Griffin says they plan to roll out the Instant Deals program throughout the U.S. and the world in the coming weeks, so other Dollar Lunch Days may pop up in other cities. If you are lucky enough to score today's lunch on the cheap.
