Any real Texas specialties at DFW airport?
Never tried it, and the only review I have ever seen of it was when I just searched the Dallas Morning News' Guidelive: http://www.guidelive.com/portal/page?...
(The write-up's accompanying photo doesn't foreshadow 'cue greatness...)
If I recall correctly, Railhead has an outlet in Terminal D. I would probably go for that over Cousins.
However, my experience with most the the "branches" of the barbecue originals is that they bring in their meats from an offsite commissary, with pretty dreadful consequences.
Reata Grill at DFW is an outpost of Reata in Fort Worth, which was innovative in its day -- it actually got its start in Alpine, Texas --but is not much to write home about these days. In addition to the airport location, I think Reata has also begun a national expansion; I found mention of a Reata Grill in Woodland Hills, Calif.
The crop of new restaurants in Terminal D (the main international terminal) at DFW is a welcome upgrade from the days when Chili's To Go and Pizza Hut were the acme of food at the airport. However, I would caution you that most of these places remain on a par with what you'll find at SFO or SEA ... or any other large airport that has upgraded its food offerings in the last five years.
All that said, if you have the time, jump on the sky train and explore the offerings. I think there is at least one barbecue place (Railhead); Blue Mesa (pseudo New Mexican) has an outpost, and there are other limited-menu versions of local places like Cool River (steaks, salads, etc.)
Please report back!
