It didn't seem to me, during my brief struggles with the door, that the issue was an inside/outside atmospheric pressure difference. if that was the case then the force required to open it would drop dramatically as soon as it was open a few inches. It felt much more like the primary issue is with a poorly designed/installed/adjusted door closing mechanism.
If they really have a much lower pressure in the building, compared to outside, I might be wondering if they have a gas supply to the kitchen, or are they all-electric?
A revolving door would have equal opposing forces on each side, if there were pressure issues.
There used to be a charity shop in the town that had a sprung door that banged shut every time someone entered or left. One day, I offered to fix it for them, if they had a screwdriver that I could borrow for a minute - it only needed the latching screw to have a tweak and it would have been OK. They decided that they couldn't allow this to occur, for "insurance issues" - so they put up with it banging shut for about the next five years before the place finally closed.
