Dear nalmehairi,
Thank you for sharing your feedback with the Tripadvisor community!
I was disappointed to read about your experience and that we failed to impress you in terms of cleanliness and variety at breakfast.
We sincerely hope to have the opportunity to welcome you back to Park Hyatt Zurich to turn the last experience around.
Please feel free to contact me at any time directly, if I can be of assistance.
With kind regards from Zurich,
Jennifer Chow
Director of Rooms
