I think things jump the shark when in the manner of "the measurement becomes the goal" So, like if something incidentally attracts some tourists that's great --but once the location targets and begins to specialize with tourists in mind, then it's changed, for the worse, with respect to the local community.
And as far as malls go, those are also dying in large numbers in the States now that their traditional department store anchor tenants are shriveling up.
So on reflection, no, I doubt it could stay open!
LA - Grand Central Market
NY - Chelsea Market
PHL - Reading Terminal
BOS - Boston Public Market
The problem is, unlike Grand Central and Reading Terminal, a lot of these markets are overpriced and end up being shopping areas only for the rich or tourists.
