ATM and Currency exchanger in MRU

How do atm work in mauritius ?
I have Euros loaded in my travel card... so if use an ATM, how much will I be charged for my transaction in MUR ?
Also, is it better to go to the money exchange companies like shibanifinance or use the atm (Which one will offer better EUR --> MUR conversion rates)

P.S. Looking to save money (even a single rupee would matter)

I see you have so many questions!!!
exchange rate for euro at shibani is Rs38.30 as at today... I don't know how much the ATM will charge you for each transaction you make with your card, i suggest you find out with your bank in India so that you do not get any surprises if ever you use it.....
