On rainy days we often drop by the Marcipan Museum in the Hilton Hotel, just to spend some minutes inside escaping the rain. The entrance fee is only 400 Forint, and it is quite fun to be there, and therefore it is a nice activity during a guided tour on a rainy day.
In May we have had plenty of opportunities to do so, as we have had a lot of rain, and below you can see some pictures from such a visit. More pictures from the Marcipan Museum can be found at the Marcipan Museum page.
