The Oldest Italian Restaurant in Des Moines?

In most cities, especially out east, you have a long list of restaurants that have been around for 50 plus years. Here in Des Moines, we don't really have that same dining traditional. The majority of the places to eat around here have only been around at the most 10 years. So that got me thinking. What are some of the older restaurants in Des Moines? The list I came up with seemed to be a list of Italian restaurants. So then I set out to find the oldest Italian Restaurant in Des Moines. Here is what I came up with:

Gino's: Established 1966
Mama Lacona's: Established 1957
Tursi's Latin King: Established 1947
Noah's Ark: Established 1946

So there you have it. According to my research Noah's Ark is the oldest Italian restaurant in town. If anybody knows any different, let me know.
