My favourite eatery there is Ippudo, the 2nd overseas outlet of the Japanese Ramen King's chain of restaurants. Go early, at least before 12 noon, if you want to avoid queuing.
Wild Honey all-day breakfast place is also very nice, thougfgh not cheap ($75 for 2 persons) but I like the Tunisian breakfast set. NY set is also nice with sturgeon omelette and bagels with cheese.
I have not tried Thai Thai - it looks nice. A friend tells me it's a Malaysian-owned place. Not cheap.
