It’s easy to miss Altair, a cozy, below-ground teahouse on a sleepy side street in Budapest's Palace Quarter, but you shouldn't. Defying space limitations, they've squeezed in myriad tiny nooks and crannies that are separated from one another by curtains, pillows, and wooden beams. This faintly lit labyrinthine haunt is an ideal date spot, offering a bit of seclusion from the hustle and bustle of the city center just minutes away. Besides the almost 100 types of teas, including black, white, oolong, and green teas, Altair also has a selection of (hot) wines, beers, spirits, and hookahs (water pipes). Note that there's a no-shoes policy, so make sure your socks are on point.
