Common questions

Which days can I buy foi thong here?
Friday, Saturday, and Sunday, from 16:00 to 21:00, in Pratuchai. Monday to Thursday the row is dark.
How much is a piece?
Ask the stall. No piece price is posted. Buy a small box and eat it that night, because the threads are egg yolk and syrup.
