I'd think there's gotta be a better solution before things come to that.
Well, for whom? If you have the contract that says the rent is a quarter of the market rate why would you agree to pay more?
I'd say you want to be paying a market rent so that your landlord is happy with you. It's in their incentive to keep you there and happy, and they're likely to go out of their way to keep you happy. If you manage to get locked into a contract to pay under market rent, then they will be unhappy with you and motivated to go out of their way to hurt your business and make your life difficult.
Granted, this may not be that common of a viewpoint in the restaurant industry, though. Or in the NYC rental industry.
This can work depending on the extent to which the contract is underspecified. You will note, for instance, that the hotel cut off room-service access to this restaurant. Clearly they didn't specify room-service availability in the contract, and so on.
Probably. The landlord probably got a premium up front, too, for it being associated with a hotel.
The contract probably had bumps, but there were probably limits to the bumps and the real estate got more valuable faster than the bump limits.
This is a good lesson about contracts. A contract is only as good as the money you can expend on lawyers to defend it.
