From Monday 1 August to Wednesday 31 August, show your Opal card when you purchase a meal at The Atrium, (from 7:00 am to) before 10:30 am or after 2:00 pm (to 4:00 pm) to receive $5 off.
Participating stores: Guzman Y Gomez, Costi’s Fish & Chips, Bun Me, Little Tokyo, Swiss Deli, Simply Noodles Malay, The Gozleme Co, Wokky Chan’s Chinese Kitchen, Mirchi, Urban Taste and THR1VE.
Edit: I see that the T&Cs allow retailers to rescind the offer, maybe when they have spent all their promotion money, so might be an idea to show an Opal card and ask before ordering. The Atrium is open on Saturdays but only a handful of stores are trading.
That's a pretty sweet offer, especially for office workers in North Sydney.
It's unfortunate that no one has posted it until Aug 20 though! (not a complaint, just saying)
