I think Mr. Starr found something we all ignored! I think Dubai is a winner. And I think they flew United. And well see some Ferrari World coverage in the morning!
Here is the thing.. Wagamamas' for the most part look the same.. The interesting thing about the picture of Elissa is that the all of the seats run parrellel to the open kitchen.. In most Wagamamas they run perpendicular except for the row of tables closest to the bar or open kitchen.... Mr. Starr's photo looks like the picture, but since we can't see the entire seeting arrangement in his photo, you can't confirm it's the same place (unless you see something I don't).... The key to authenticating the Wagamama as being in the UAE is the Christmas Tree (artificial, done in white, contemporary, cosmopolitan) and the cylinder shapped chrismas presents (apparently very common in the UAE check out google images) and (puts on the racist hat) the cash register operator....
Edited to also mention.. If they were flying delta, with their status (medallion level w/e) they wouldn't be flying economy on a long flight.. They would definitely have gotten a free upgrade (or used points to get a cheap one) on a long redeye flight.. No matter where their destination might be..
