There are 261 reviews of the Grand Budapest Hotel on TripAdvisor, the #1 hotel in Zubrowka.
As one review puts it:
We had exciting dinners in the Grand Alpine Restaurant and after that usually some cocktails in the recently reopened Lutz Lux Cocktail Bar for a few Klubecks, as Zubrowka is not yet part of the Eurozone.
In case you are looking for Van Hoytl’s “Boy with Apple”: the painting is to be found in the hotel’s Secret Gallery these days. Just ask the helpful concierge for details.
