For a change, I'll have sort of milk shake - no, I'm feeling OK. LOL!

It's gonna be a bit of a challenge perhaps? I had it in a hotel (mornings) called Riu Merengue. I asked the ingredients, but as my spanish is not perfect, I'm not sure I got it all. Two things in it was bananas and milk. - (the bananas used, we may not be able to get here.

Can you sort that one out??
