What does "dine on Crow" mean? The word crow is capitalized and it seems to be an expensive restaurant, I am not sure. Considering the author said in text with "sitting down to a heaping helping of Crow", it seems to mean a luxurious activity - a festival. Wikipedia explains what is "eating crow" - "Eating crow is a colloquial idiom, used in some English-speaking countries, that means humiliation by admitting having been proven wrong after taking a ..." - yet the crow here is not capped. The best guess I have had now is that the crow can be either capitalized or not, the meaning is exactly what Wiki explains. I am not very sure.

You are reading what is essentially an op-ed, if that. I would be very surprised if it passed through any copy-editing process. See the note at the top of the post:

It is not common to capitalize the word "crow" in the idiom "to eat crow" which means, as you have discovered, "to admit being wrong, usually in a humiliating way." It could be the case that there is some person called "Crow" mentioned in the post and the article is making a pun on their name; you can see that is not the case, so my guess is that the capitalization is a quirk on the part of the author.

"Dine on crow" and "sit down to a heaping helping of crow" are not established idioms in their own right—but they are recognizable as being fancier wordings of the standard idiom.
