I'm looking for recommendations for mid-range priced restaurants for Sydney. We had selected Barangaroo House, but when I went to reserve, the reviews are less than stellar. We have six nights in Sydney. A couple other restaurants I'm looking at are The Malaya, The Opera Bar (website indicates they also have food) and Mamak. We don't mind venturing out a bit from our hotel on the border of The Rocks and city center, for example, into Haymarket. In general, we like Thai, Vietnamese, Malaysian, Chinese, but also interested in trying local offerings, except fish and chips and meat pies, which we had our fill of in England. My husband also is typically on the look out for lamb and duck.
I have done a search of the forum. Other than a previous post of my own, posts are quite old. Also we arrive on a Saturday, mid January. Are reservations generally recommended?
