Ventured to Whampoa Food centre (Blk91? nearer to market), and discovered there are 2 Vegetarian stalls, both popular with long queues on non popular Vegetarian days (Lunar 1st & 15th day of month). Good signs of popularity of Vegetarian amongst the people. :-)
Decided to try Keat Lim Vegetarian, which serves standard fried Mee hoon/Noodles dishes and a number of Delicious looking vegetable dishes and fried stuff. Nice noodles, especially with good choice of vegetables and braised mushrooms and well-fried Wuxiang roll. :-)
