Apparently Mighty Bird wants you to try their tacos and Favor wants you to know how their service works, because the two Austin-based companies are teaming Tuesday to deliver free breakfast tacos from Mighty Bird on Tuesday. The promotion starts at 9 a.m. tomorrow. Favor users can get two tacos (a bacon, egg and cheese and a bean, egg and cheese) delivered ,and while the tacos are free, users will still be prompted to tip their drivers (I’m guessing in the $3 area). Wondering if you can get in on these? Check out Favor’s delivery zone.
