The Budapest Zoo and Botanical Garden opened its gates in 1866, which makes it one of the oldest zoos in the whole wide world. It houses several iconic establishments, such as the Palm House, the Elephant House, and the 100-years-old heritage merry-go-round. Most of the significant buildings were designed by the noted Hungarian Art Nouveau architect, Károly Kós. As the Budapest Zoo is home to about 773 species of amazing animals, it is recommended to spend a whole afternoon here. If you get hungry after so much strolling, a delicious steak at Robinson, or a palatable pancake at Gundel is always a good choice.
