As Thai food isn’t given much of a limelight in Singapore, I thought I’ll recommend one.
Of course we’ll all familiar with Thai Express. Here’s one that isn’t too pricy. It’s located along the MRT track between Yishun and Sembawang. Take the train and look out for their banner (red). No known bus which goes there. It’s good to have a little exercise before eating. Do try out their pineapple fried rice.
