I came across Thai Essence via Groupon, and a deal that allowed 2 people entrees, main, drink and dessert for approximately $38 total.
I found the decor to be stylish and fitting, the food (red curry and spring rolls) was tasty, good serving sizes and flavorsome. Fresh in taste and very palatable. The service was adequate.
Free parking can be found a 60 second walk away at the council car park which is also on macquarie st, right near D'Roost.
