I have updated my post upthread to mention that Gordon Ramsay pulled out of providing restaurant services (as well as lobby bar and room service, which he stated had contributed significantly to that location's financial losses, in a recent article in, iirc, the IHT,) at the Hilton Prague Old Town; Ramsay basically sold the restaurant back to the hotel.
An article in the Prague Post says more, as do
this one in the Times online and
this one in the Scotsman online
If anyone stops by, please update us on the restaurant and new providers.
