While on the subject of restaurant chains, I work in St Kilda road in Melbourne and have in the past found few good possibilities for a LC lunch - when I don't have time or inclination to bring a lunch from home. (I am known as the container queen at work!). It is difficult to find something other than a sandwich and some of the salads are just deplorable!
However late last year I found a gem called MYO - so wonderful for LC. They have all the makings for any type of salad you can imagine and all sorts of cold meats, eggs, condiments etc and you just put your own meal together in whatever size container you choose. Only issue is at $6-80 for a medium container it can get a little pricey but everything is very fresh and there is just so much choice. I think there is another of these chains in the city and from memory there may be one in Perth - will check when I go get lunch today and post the locations if anyone is interested.
