Boticario is one of the so-called "speakeasy" bars that are present in buenos aires. NIce spot to go for author cocktails with a great presentation and nice atmosphere. It is located in the heart of Palermo so if you want to continue your night somewhere else, this one could be a great start
It's something new in Buenos Aires out of the already known with very good cocktails and a cool atmosphere.
Be careful when you reach the place as being a speakeasy bar, will only see from the street something like an old pharmacy and one security.
