A historic building suffused with light and harmony, comfortable leather armchairs and stylish modernity—that’s Dylus, a place to chill and chat, boasting Germany’s only water bar serving an assortment of waters from around the world. Or try the coffee, which is among the city’s best. By the way, we’re not talking about a café. Dylus is an exclusive beauty salon near the Frankfurt stock exchange—a celebration of hair and a feast for the senses.
