Budapest, Hungary

With some of the best Art Nouveau architecture in Europe, scenic Budapest has no bad angles. Explore the Hungarian capital’s spa culture with thermal baths built in the 16th and 17th century, and make sure to pay a visit to the ornate New York Kávéház for coffee and a pastry. Walk the Széchenyi Chain Bridge at night over the Danube River for magnificent views, and eat a bowl of traditional gulyás at the three-level Central Market before turning in for the night.
