Zummo's is from my hometown of Beaumont, Texas. SW Louisiana and coastal SE Texas share quite a bit of that Cajun culture. I have unsuccessfully tried to persuade Zummo's to send their delicious Party Time Hot Links to my current home in Colorado. If you're here and you work for Zummo's, please listen to my plea!
The River Parishes (St. Charles, St. John, St. James) are pretty much their own region too. It's a mixture of New Orleans and Cajun plus a healthy dose of German.
