This might just be the world’s grandest greenhouse, taking up most of one side of the pretty Burggarten park by the Hofburg. Home to towering trees and plants from around the world, the Palmenhaus doubles as a restaurant and bar, serving modern Austrian specialties like Schnitzel and lighter Mediterranean bites and cocktails. It’s super-central, so wherever you’re staying this is a great spot for a memorable first-night dinner or drinks.
