Let's start with the positives. They offer microbrewery beer on tap, its actually quite nice, and before 9pm it is reasonably priced (S$8.9 per pint) for Singapore. The ambiance is pleasant.
Hmmm.... cant think of any more positives. So on to the negatives...
The service is slow. Often didn't see my server for 30 mins or more. I wouldn't mind if the food was worth waiting for. But it was not. It just doesn't taste how it should. I don't know if has been toned down for the Singapore market, but it lacks those gorgeous flavours of the middle east. The kebabs from Shiraz are much better, and even their kebabs I would rate as "average".
That said, the restaurant was quite busy. Taking a look at the scores for this restaurant, it is quite an unusual profile, quite polarising. In other words, some people love it, whilst others hate it. Well, I am definitely in the hate camp. But you may well love it, you can only really tell by giving it a try. But it doesn't come with a recommendation from me!
