for food suggestions, perhaps the more adventurous of you might want to check out the “untourist” places, like coffeeshops along joochiat road, there's a really good south indian restaurant called gandi on the back streets of serangoon road and more.
pm me if you're interested in more food-ventures.
p.s had a look at the website. food at newton circus is over priced. an alternative location might be “chomp chomp food centre” at serangoon gardens.
