I was in NOLA a little while back and was offered a beef tongue taco...my first thought was HELLS NO !
then I thought...wtf...I need to be more adventurous....so...I ordered them.
My expectation was that they would be chewy like squid...not sure why...it's just what I thought tongue would be...I am happy to say that it was tender and tasty ! Not at all what I expected.
I would definitely have it again.
Here's a picture.
