hey guys..
there's one very good stall of vegetarian cooked food at Hougang. Take bus 165 from Hougang Bus interchange, alight after you see the Hougang Stadium. It's in the few blocks of HDB flats just across the road. there's one block there with some shops on the ground floor.
they are open everyday, even public holidays. they serve all kinds of zi char - fish, vegetables, gong bao ji ding, and even chicken rice, roti prata, ramen (they make the ramen themselves by hand). our favorite is their mutton curry ramen. they also have niang tofu, roti john, rojak, etc...
All of the above are vegetarian. i often go there with my parents.. 3 of us just order a few dishes to share.. the bill is always between $15 to $18 at most. even their drinks are home-brewed. from sour plum, chrysanthemum, etc... a wide range to choose from.
go during their dinner time.. they will have a wider variety. lunch time is quiet, and the main chefs are not around. they are always crowded.. there's not much space inside the shop, so they set up not less than 10 tables along the void deck. the best time to go would be after 830pm, when most of the crowd are gone. but they will still have alot of food.. no worries.
highly recommended
