At 2pm on Monday afternoon, 5 of the 7 customers in the naughty chef ordered "no.7, hot and spicy soup".
Having read the "three of the best" review in good living, I've been ordering this quite a bit recently. I've tried it at Pho Ben in Parramatta, and the new Orange coloured Vietnamese next door to Pasteur in Haymarket. Here, the broth is fish-based, but not overpowering. It's quite tasty. The best salad selection came from the Orange-coloured place, whose name escapes me.
Post-post note: The Orange coloured place next door to Pasteur is called Gia Hoi. I have also just tried the Bun bo Hue at Xic Lo around the corner. I have to say I was a bit disappointed at Xic Loc, because it didn't come with the plate of brightly coloured salad and cabbage, and there was barely any hint of the fish based stock.
