Let be honest, if you decided having dinner at Stanley, Murray House would be the ideal place, $200+ per person should be something you expect since the location and the sea view itself. Foods there are above average, but with that kinda pricing and atmosphere, don't expect much surprises. The Vietnamese restaurant (Saigon) has fairly standard Vietnamese, good presentation, but then again, taste are standard. I tried the German restaurant the other day, pork knuckle and the mixed sausages are fairly decent, worth taking a try if you are there.
If you are there during the day, you could try walk down and pass the main street, next to the football court, there's a small burger shop which make fairly tasty burgers and hotdogs, around $60-90, the only down side is they uses cheap buns, which kinda disappointing.
