Why the winner leads
Why Cash Only Diner ranks #1 for dim sum
The chilli har gao at Cash Only Diner bursts with a vibrant spice that lingered pleasantly on the palate, alongside generous toppings of fresh coriander and a delicately chewy texture. Reviewers noted a comforting aroma and substantial portion size, suggesting a focus on generous servings and a satisfying experience reminiscent of traditional Cantonese yum cha. Unlike many Sydney dim sum offerings, this establishment’s Vietnamese-influenced style, particularly evident in the uniquely flavourful poached chicken salad accompanying the dim sum, creates a distinct culinary identity.
