Attending an event near Choa Chu Kang MRT, searched internet in vegetarian food at Choa Chu Kang and upon enquiry with Friend staying around the area, they all pointed to "Go Vegetarian" (Blk 303, Choa Chu Kang Ave 4) at Foodfare food court located at block right turn from the MRT.
As I was rushing for time, I took their most convenient economical rice though their Stir-fry dishes were more popular according to internet.T
The rice was dry but the vegetables were of reasonable taste and the otak was good though.
Queue started to form for their Stir-fry dishes when I left. Next time if I ever visit the area again...
