Just 5 bus stops or so away, there's the bedok reservoir blk 630 market.
Here, there's Xiang Ji chicken rice which is really the classic "cheap and good", going at $2/$2.50/$3. It's the most popular in this market so expect a queue!

On the next row, there's the mouth-watering Cheng Fa Fried Kway Teow (back of picture) going at $3/$4/$5. Also, there's a really nice drinks store beside it, remember to order their Teh Ping it's really good!!!!!!!!
