This make the B2B stuff easier, as many malls are owned my massive groups that run even dozens of malls - and they can make a contract with a large franchise operation to cover many/all of them (or a restaurant group that can provide different options). They also don't have to worry about risk on the rent much.
Notice how food quality etc. didn't show up in previous para?

(“Morgan Street Food Hall is a new lifestyle dining concept; not to be confused with a food court.” Ugh I almost didn’t visit the place since the web site is so fucking pretentious.)
I first visited one of these in Chicago.
My preference is a city park surrounded by food trucks. But these aren’t reliable, only work when the weather is good, etc.
