I don't think so, for most food courts are leased by the individual restaurants that want to be located there. In that situation, as with the stores, they are considered individual entities. A certain area is leased and designated for the purpose of selling food and alcohol.
Now, as the seating area is a common area for the restaurants, that section could be up for debate on whether or not it is off limits. For it is conceivable that you would go to a full service restaurant that sells alcohol and get a soft drink or water, however, the restaurants sells alcohol for consumption, therefore one can say, even though you went to McDonald's in the food court, the steak 'n ale located there sells alcohol for consumption in the same area.
As far as I know, most malls do not allow for the consumption of alcohol outside of designated areas, especially in the individual leased sections for the stores. Therefore, they are not considered part of the food court. Just like we can carry concealed at the grocery store, but must open carry if we decide to do business at the bank while we are there.
