Andrew Zimmern wasn't here this time, but the Travel Channel was back in Birmingham this past weekend to film segments that will possibly air on the globetrotting chef's new show "Bizarre Foods: Delicious Destinations."

Film crews for the Travel Channel were scheduled to visit the Irondale Cafe and Ezell's Express on Sunday, as well as a few other locations in the Birmingham area.

The "Delicious Destinations" crew was interested in the histories behind the Irondale Cafe's famous fried green tomatoes popularized in Fannie Flagg's book and movie and in Ezell's legendary fried catfish, which goes back to the original Ezell's Fish Camp that opened in Choctaw County in 1937.

The restaurant owners signed non-disclosure agreements that prohibited them from talking to the media about the Travel Channel's visit, and a representative from the network contacted by AL.com declined to offer specifics about the "Delicious Destinations" trip here.

Zimmern -- whose other Travel Channel shows include "Bizarre Foods with Andrew Zimmern" and "Bizarre Foods America" -- came to Birmingham three years to film an entire episode of "Bizarre Foods America" here.

During that trip, Zimmern visited Eagle's Restaurant, the Red Pearl, Niki's West, Miss Myra's Pit Bar-B-Q, Hot and Hot Fish Club, Jim 'N Nick's Bar-B-Q and other locations.

The segments filmed this past weekend in Birmingham could air on "Bizarre Foods: Delicious Destinations" sometime later this year.
