Majuki in my recent trip to Budapest I avoided Euronet like the plague.
Near Rakoczi Ut there weren’t many non-Euronet ATMs to chose from. They all had an operators fee one way or another, but at least didn’t try and force conversion. I think the missus and I settled on OTP bank, and unfortunately we seem to have added to the long line of locals who also seemed to use that ATM and no other.
