Re:Has anyone ever eaten any of these dishes?
I've eaten similar items at several local restaurants and in Washington, D.C. and other places and I will again. My main problem is that I tend to be a little more adventuresome than some in my family. One order of pork kidney in garlic sauce - to name one example - is a lot if no one else will taste.
If the restaurant you describe has a web site I hope you will post a link.
I've had a couple of unfortunate experiences over the years.
We used to stop for BBQ at a place north of I-10 and the food was pretty good. I used to think it would be nice to pass through on a summer weekend when they advertised live music in the evening. Then one time I bit down on a hard something in a BBQ sandwich that was made from what I assume was nicely seasoned local sausage. I thought it must be a piece of bone that went into the grinder. It turned out to be an intact kernel of feed corn. I am sorry for the folks who suffered so much in the hurricane, but I'm not sorry that BBQ place did not reopen after Katrina.
Then there was an unusual take out soul food place run by Americans in Atlanta once. It was a recycled hamburger stand if you will and had a drive thru line. They served good chitlins in hot sauce and one day I found a piece of more or less intact silage, a husk fragment in my container of food. Never went back. That place is no longer in business either, SFAIK.
