The almond longan tofu for $2.10 at the Hougang Mall food court is so not worth it.
The base is all shaved ice and you get four pieces of tofu and four pieces of longan.
If you want great soft flavoured tofu, the store towards the rear on the left side as you enter Chomp Chomp eating centre is great. They have different flavors too besides almond.
Go to Serangoon station and take the 315 or 317 bus. Tell the driver you want to stop at Chomp Chomp.
