Taco Cabana met their Tweet2Eat Twitter goal last night, with 500 tweets containing the hashtag #addicted2TC. And now, we can all reap the rewards! Today only (Aug. 17) you can print a coupon to get a free 3-Pack of Street Tacos. There is a limit of one coupon per customer. I have been able to redeem my freebie at the drive-thru window. This offer is only good Aug. 17. I know where I’m going for dinner tonight!
