Hotel and Restaurant Museum (Hotelli- ja ravintolamuseo, Hotell- och restaurangmuseet) is a special museum. It tells about food & drink culture and tourism in Finland. Admission is free with Museum Card, Helsinki Card and visitors under the age of 18 years.
I learned interesting facts in the museum. Here is one example. In 1943 we got a law that says that school lunch must be free for every pupil. So Finland is the world's first country, which started to serve a free hot lunch for every pupil 1948.
