Deletion of Milwaukee-style pizza

Comment: I found http://www.milwaukeefoodtours.com/featured-post/2015/11/14/milwaukee-style-pizza but overall the sources are few and not particularly professional. It does seem like mostly promotional / social media catchphrase. I cannot even load 2 of the 3 sources, but the one I can is again, not particularly good. Does not seem to meet  IMHO. Having opened the other 2 sources (they just load very slowly), they do seem to mention and define the concept. However. the coverage is limited to Milwaukee Journal Sentinel and some blogs/promotional sites. I am not sure this suffices for a food to gain notability
