Went to Tampines again and the nearest vegetarian stall within Tampines Central seems to be only "Just Green" at Eastlink Food court. It does have a great variety of dishes to choose from, especially on bean curd dishes that I always couldn't resist ordering. Their next speciality is their 3 sticks of satay at $1.50. I would think their satay mock meat texture is well-marinated & has great resemblance in chewiness and taste to the real stuff. Worth trying especially for those who used to love satay.
It's good that they also serve free soup during lunch as that really warms one dining at the unusually strong air-conditioned food court that chills.:-P
