If you love steak def go to No.35! All very good food ... If you have club lounge access, I would recommend it.
I have to agree No.35 is the best restaurant with beautiful views of the city.
No 35 is excellent. As mentioned by Beau there are many great restaurants within walking distance of the hotel. The concierge will help.
Never try that both restaurants, i prefer eat in outside, there is a lot good restaurants in lygon street and Bourke street
