I've only eaten at once near the Opera House, so I can't honestly say if this is the best. But I liked the meal I had at Wild Ginger. Really close to the Opera House, Wild Ginger is best described as Vietnamese Fusion. (but there's also a Thai flavor to it) I had both satay, and a beef dish--but I don't remember what it's called. While flavored well, the meat was overcooked and pretty rough on both accounts. There was a noodle dish I loved and the manila clams were to die for!
