Caras y Caretas,

Restaurant & Bar

Inaugurated in October 2018, the Caras y Caretas bookstore is, without a doubt, one of the most endearing and special spaces in our hotel. A place to enjoy the best literary works and cultural activities, in the company of a great gastronomic proposal.

Hours of service from Monday to Saturday from 08:00 a.m. to 10:00 p.m.

An unforgettable experience in Buenos Aires.
