We visited Mystique on Valentines night when they were offering a set menu of 3 courses and a glass of fizz for $50, which is very reasonable.
The food was of a good standard with a varied menu and some creative dishes that made the most of local ingredients.
The restaurant was very busy as it was Valentines night and as a result the service was a little hectic at times, but it was quick and friendly. I got the impression that they were under a bit more pressure than usual due to the large number of diners eating at the same time, which may have explained the slightly more rushed service. That said they were cheerful and friendly throughout.
They had a live musician on the night, who was good, but only played a few songs in the 2 hours that we were there, which left the room lacking background atmosphere in the long breaks between bursts.
Overall Mystique was a good place to eat and we enjoyed our food, but I have a feeling that on a normal evening when the staff were not so rushed it would be excellent.
