A must see if you are in that area.
The bus ride alone is worth the trip. We went as part of the Trafalgar tour so everything was looked after for us. The view was spectacular. The guide talked quite a bit about the history of the place. The restaurant is quite "American" . But, you have to look past things like that. Concentrate on the view and take many pictures. Try to go when the weather is clear.
