On-Line Cafe/Food at DTW
In the McNamara Terminal (delta Mid-Field Terminal) I like the On-Line Cafe for breakfast on Concourse A. They make good omelettes.
When it opened in 2002, it was innovative for having internet terminals at most booths, but with the advent of Wi-Fi and 4G, I rarely see anyone using their computer terminals.
Regardless of the computer, they are relatively prompt in preparation for a complete breakast for eat-in with waitress service, or boxed to take on the plane.
I agree with the previous comments of the Concourse C Fuddrucker's... decent food, but suprisingly slow preparation.
If you have more time, I suggest DEMA in the Westin Hotel. Very good food, great beverage selecton, high prices, and private security line to re-enter Concourse A.
With the decline of the Sky Club snack offerings and poor availability of SkyMiles Awards, I have been using the Star Alliance carriers more frequently since January. They operate out of the North Terminal (Continental will join them later this month); I have found Ruby Tuesday's (near the US Airways and Southwest Airlines' gates) to offer higher quality food than Chili's or Max & Erma's.
