I’ve had them when traveling, a couple times at Lone Star (hey, when you are on the road, sometimes you just want to eat and get it over with).
It was reasonably tasty; a lot like a local steak some of the supermarkets around here sell called a "charcoal steak". I actually think that one is kind of like a chuck steak.
If either is not cooked beyond medium rare, they were decent for the price. Hey, it’s not porterhouse, but for half the cost, it was OK.
Then again, I like beef, period.
