Good point @nimbex1970 The prices are in Euros. It's 24 euros for guacamole and chips. I live in NY, one of the most expensive states, and it's cheaper. Rainbow Cafe does look nice though. Perhaps, we just rent chairs and get drinks, and share the guac and chips. It also like like there may be food trucks in the area.
I know there are taxis by the port but maybe, we are better off pre-arranging with one of the more reputable companies.
