The renovated Mustafa's is a kickass shopping centre, man. It is open 24 hours, has a huge supermarket (but no rice milk I was desperately looking for for my Faith), has a bookstore, electronics and hardware departments, and is new and swanky. At least the new 2nd to 4th floors were.
I ended up buying the rest of my groceries there, like diapers (XL, L and Newborn!), wet wipes, and baby bottom cream. Small point on merchandising and product placement... don't make me go to the 3rd floor for the diapers and wipes, then B1 for the baby bottles and the 1st floor pharmacy for the Balmex nappy rash lotion.
Oh, and they use this technology not seen in many supermarkets these days. It's called a price tag. Imagine that, real human readable numbers on every price tag. Love it.
I commented to the cashier on the busy night despite the next day being a working day, and she said with late shift wry humour, "Every night busy. Singaporeans don't sleep."
