Circuit Road Hawker Centre has an abundant amount of vegetarian food and this wanton mee ($3.50/$4) from Meng Heng Vegetarian Food is one of the best I've tried. The noodles is the star of the dish, due to its firm texture and the chilli sauce that coats around it is really addictive.

The Vegetarian Otah ($2 per piece) from Victor Veggie is interesting as well and has a nice spicy kick!
