    Spicy Cajun Crawtators

    Zapp's is a regional chip brand based in Louisiana. You can find them nationally if you search hard enough. Their top seller is a flavor that's reminiscent of a bayou crawdad boil (similar in theme to the Old Bay-spiced chips). Zapp's claims that their Spicy Cajun is the first Cajun-flavored food item ever produced.

    Earthquake Chips

    Another regional chip-maker is California Chips. Their 'Earthquake' brand will shake up your perception of what makes a tasty chip. Their formula is a secret, allowing only that the Earthquake flavor is a combination of other popular flavors. Tasters claim you'll get hints of barbecue, jalapeno, salt & vinegar along with sour cream & onion. Wow, that's an 8.0 on my Richter scale.
