They have a good few branches throughout Ireland. (no connection with them).
I used a Visa debit (BOI) card last month there and was given a dismal rate, plus an overseas charge and the biggest allowed single withdrawal (without going into the bank) was $160 at the ATM !!!
Your bank maybe different.
Hard to know what to do as I don't like carrying too much cash, but the Visa debit was accepted everywhere albeit with problems in some retailers.
