I´ve been to a "Sizzler" once, and that one time was one time to much!
The one I´ve been in Kissimee was very dirty and the food they served wasn´t even eatable (notice: I´m NOT picky!!!): all dried out, the salads looked like they´ve been at the buffet since days, the soda-fountain was only running with coke, nothing else.....
I don´t know if I made the experience with a very bad "sizzler and how the "Sizzler" in down under are, but I can´t imagine that I´ll ever give them restaurants a second chance.
