I believe there is one at Royal Garden Plaza.
Yes I remember seeing the PEA office there but at that time I didn't know what services PEA offered.
Had a meal at the food court at the top floor which I think was previously a cinema. The food court has Indian, Russian, Chinese, Thai, ...etc food. Surprisingly I found the food tasty.
Foodland has a new outlet at the ground floor. Like all Foodlands the place is open 24 hours.
