I fly pretty much exclusively weekdays, the two I usually hit are the e terminal and the c terminal on the old side. Just due to the gates I'm flying out of. They are pretty much always completely full. That's why you see the "no one time passes" signage out front. Maybe disgusting is a bit harsh, but I compare it to their offering at the other hubs (ord,Newark,lax) where the food selection is 1000x better. Stale sandwiches and soup seem to be the common offering in Houston. Pre COVID was much better.
