I assume you're referring to the Inventions food photos in the trip report?
If so, those were actually taken with a Sony RX100 point and shoot. Those photos were easy because the lighting in the room was good. I just used macro focus with a higher ISO and got the shots. I almost NEVER use flash for food photos.
It's not always that easy. My shots from Blue Lagoon are awful. The lighting in there makes it really difficult.
I wrote an article on food photography for Disney Food Blog a while ago. That might help:
