Most of the stalls in hawker centers sell fried fishcake at $1 per piece, but this stall at ChinaTown Hawker Center 2nd floor near the center's public toilet is selling fried fishcake at $0.50 per piece. Minimum order is 2 pieces.
I am pretty sure the margin per piece has been squeezed but they make it back by selling more. Last Friday, while I was there I bought 20 pieces.
They have two stalls side by side. If you are only buying fishcakes, you don't join the long queue for yong tau foo; but go to the stall on the left.
