I had an appointment to meet a friend for lunch @ central station, but that got cancelled, so I wandered off to find another place with good reviews on womo.com.au [roughly 30 min walk from central station along George St] & ended up at the food court in Queen Victoria Building .. after scanning different menus & prices, I decided to go for something out of the ordinary for my diet & thought I'd give son of Tuysuz a try! after all, I'd heard that middle eastern food was yummy but never actually had any .. I was NOT about to be disappointed! :) for $9.50 i got a kofte burger [lamb] which was BIGGER than most burgers you'd get in a normal food court, + salad which filled me up plenty for the next 4 hours, and I walked a fair bit around the CBD on a warm enough day, so i thought that was pretty good value!
if you got a smartphone, they're running a free meal deal in the food court in Queen Victoria Building if you download the app & try 4 restaurants, i think you can get a free meal =) *rats*, if only i was staying in Sydney a little bit longer ;P

Approximate cost: $10+
