Other languages aren't really prominent. Quite a few Brazilians, so hear the odd bit of Portuguese from time to time. It's Spanish or English basically.

Uruguayan/Argentinian spanish is a different ball game than others. It's understandable but they of course have their own words for avocados - palta instead of aguacate as an example. And playa is pronounced plasha. Still coming to terms with it, but people are patient & forgiving.
