I've only been to Rush at noon for business lunches. I have never been disappointed by the quality of the food or service. The restaurant is large, very modern and exquisitely designed. Just love the cellar and incredibly wide selection of excellent wine.
While the ambience upon entry appears pretentious, the friendly welcome and attentive service dispels any notion that the dining experience is going to deteriorate over time. I've enjoyed the innovative and fresh dishes and the ability of the staff to suitably romance the dishes when describing the specials and when the dishes are brought to one's table.
Pricy yes! But this is equivalent to a comparable modern European or International New World Restaurant. I would have no hesitation recommending this Restaurant to seasoned international business travellers.
