I've noticed that at Causeway Bay station the Hang Seng ATM area has lots of multi-currency machines.
It's more than the usual RMB/ USD setup. They have Thai Baht, Korean Won, SGD, Euros, Taiwan Dollars etc.
Does anyone know if they charge any fees or is it at the UnionPay rate like the HSBC CNY ATMs?
If the latter, this will be an excellent place to get holiday money.
