I've been to Aruba, and I can't say I'm very enthusiastic about the place from a cultural or cuisine aspect. Just not much "there" there compared to the rest of the Caribbean. I think that is actually a reason it is so popular with tourists from the US and Northern Europe.
The popularity of Aruba is all the more remarkable given the fact that the little island is on the far side of the Caribbean from the US, making for a very long flight. It's also Chicago-flat and Phoenix-dry/dusty with hotels packed ass-to-elbow on the beach. The weather and water are very safe bets, though. I went to SteveZ's Argentine place and thought it was good. As for "local cuisine," it usually involves melted cheese from the Motherland -- I'm not kidding. Unlike Spanish, Portuguese, and African, Dutch food does not seem to have translated really well to the tropics.
But Antonius might really enjoy listening to the language, Papiamento, which is an amalgam of Dutch, Portuguese, English, Spanish, African languages and other stuff. Young Dutch ladies by the KLM-load are also a draw, as I understand it.
It's not all bad, as much of the street food seems to be borrowed from nearby Trinidad.
The local delicacy as described by a tourist site:
Keshi Yena: a baked concoction of Gouda cheese, spices, and meat or seafood in a rich brown sauce.
