Special lunch time offer - get a 1/4 chicken and 600ml bottle of Coke (or other Coca-cola beverage) for only $5.00 - save $1.00 if not more, depending on where you get your Coke / Chicken from. They've had this deal since just before Christmas, and still appears to be active - there are a few A4 signs near the hot chickens counter advertising the offer, with no "end date" anywhere. Should have taken a photo of the sign, but the receipt will have to do for now instead.
Not sure if any other Coles' stores are offering this deal, but for those who work in the Adelaide CBD and don't mind a short walk down to Rundle Plaza, this is a great deal. Hopefully it'll continue on for some time. Also, if they haven't got any 1/4 chickens bagged up ready for sale, just ask at the counter and they'll cut up a whole one into quarters for you :)
Edit - thanks to Chickenleg, I've updated the picture to show the promo sign :)
A whole chicken is 8 bucks. Coles soft drink is 75 cents. 8.75 gets you 4x the chicken and 2x the soft drink.
