There are 3 Sizzlers in NSW... 1 in Carramar, 1 in Campbelltown and one next door to St George RSL.
I totally agree that you don't know what you're eating etc... but for me when I went out for Sizzler whilst pregnant with Madeleine, I asked to be seated closer to the Salad Bar and I watched when something was brought out, and was one of the first to serve it up for myself, but only the hot foods. I'm not saying its the right thing to do.. but it is what I did.
