Marrow anyone

While in Australia, we went to the marina and in the restaurant there we got some ice cream and lamingtons (australian cake thing). While there, I was just looking at their menu and happened to see a picture of a piece of bone, and the advertisement for roasted marrow. When I was in Africa, they would suck out the marrow from the chicken bones, but I have never seen it on a menu before. It definitely isn't on my list of must try foods. I just started eating tomatoes and potatoes since I came to PNG, marrow is pushing it.
