Staff are pretty good, and the restaurant is comfortable enough. In fact the only problem is the price which is really high for Malay/Malaysian food. It does feel a bit too high to justify regular visits, but if you wanted to do a fancy-ish trip with friends it might suit you.
Their Fish Head Curry was really good. It was the only dish today that met out expectations. The flavours were awesome and the curry was perfect. I would rate their Fish Head Curry at 8/10
Update: I did return, and when not busy it was a very different experience. Staff were more friendly, and got the order right. There had also been changes to the menu to bring in more interesting options. It’s still an expensive alternative to other sandwich shops, but much less frustration means you’ll feel you get more for that money. I have upgraded the score as a result.
Overall, the taste wasn’t bad, but this is expensive, and the rigidity of the staff might get your blood pressure up. I would say if you like the look of a fixed dish, then go for it, otherwise it might not be worth the aggravation.
