I am not usually one to get to the airport with enough time to grab food, however I will grab something on layovers which makes this list of best airport dining somewhat useful for me. erc and vaboywnder according to this list Dulles is getting a Chef Geoff’s, Bar Symon, and District Chophouse within the next year. iahflyr's home base comes in at #27, kharada46's home base HNL comes in at #37, jerrycoin's home base comes in at #29, bejacob's Port Columbus comes in at #40. pluto77, californian, jm1991, misterchk and others from the West Coast have all 3 of their major airports in the top 10.
In the past month I have flown in and out of 2 of the top 12 (MSP and DEN), but did not stop at any of the places mentioned on the list.
An interesting list nonetheless . . .
