I've eaten a few times at Pure South and it is fine
Both cities are blessed with tonnes of great restaurants at all price points. Everyone here is going to recommend different places.
My only tip : forget about any restaurants that advertise in the tourist magazines that are in the hotel rooms. They are invariably godawful rubbish
When you know where you are staying, put up another post saying where you are and asking for good eats within a couple of blocks radius
