Just had a slice of "Cajun Pizza" here in NYC (apologies to Louisiana.) I know they serve it at a funky place "chain" (2 branches) called Two Boots as well as W. 12 St. Pizza.
Sorta thin crust pizza with some sort of crumby crust, available with cajun sausage and lots of veggie combos. Taste pretty good.
So where else in US do they serve "Cajun" pizza?
