Price: Cheap (on this occassion)
Service: Pass (probably better at Campbell St)
Antiblog (ZL): AH is the Chat Thai expert and prefers the Haymarket branch. We've been to both Haymarket and Westfield numerous times and agree Haymarket is better (and subsequently the line is longer) but Westfield's is decent.
PS. The mousseline looks nothing like the picture in the menu.
