Whisper Sister is my favorite cocktail bar in Tallinn. A speakeasy in the true sense, with a completely anonymous entrance area. Hint: Call the telephone number on the door. Whisper Sister has many rooms with various interior design which allow for different atmospheres. Drinks are well-balanced with a minimalist presentation. Unless you ask for a piña colada, in which case they go apeshit on you (pun intended).
