There are probably hundreds of money changers in Iloilo City. Here are a couple that I have had good luck with, good luck meaning that the exchange rates are good, the bills they have given me are good, they have not been too fussy about the bills I give them and there have been no instances of them trying to shortchange me:
My definite favorite is Valiant Bank, a rural bank that seems to do a lot of money changing. They are located on the east side of Mabini Street, just a block or so from Robinson’s. The staff are honest, pleasant and accommodating. Dona Joy (0906-450-5123) seems to be in charge of money changing.

There is another popular money changer (affiliated with Valiant Bank) in the first floor of the Casa Plaza Building which is adjacent to the Atrium Shopping Center. If you need Euros or other international currencies this is a good bet.
