Midway has a nice food court. It's not that bad.
Candidates for worse than Midway: some PHX terminals, plus it is 1.5 miles from end to end of PHX; San Antonio is cramped, Dulles, Miami.
PHX is bad. If you drive to the wrong terminal you have to get back on the freeway just to go to the right one. Sucks if you’ve forgotten your car rental agreement and almost get arrested for car theft trying to get from one end of the airport to the other - but that’s another story...
