Sounds as if the Kushners are up the creek a bit on this, as now that their second major tenant has failed. Half their rent revenue out the window between the two. Deutsche Bank could end up with the building. Either the building was over appraised or they paid too much to buy it. This forced the high rent which in turn forced high ticket prices, and caught Gulliver's Gate in the pinch. Not 'enough traffic to pay the rent. It's really not in Kushner's best interest to evict them right now, some rent is better than nothing.
I know first hand about opening an attraction in a high rent location. At least my failure didn't bring down the landlord (though I would have enjoyed that). While I can empathize with Gullier's Gate, I may yet get my wish.
