This tip is helpful to those who cannot live without the "coffee-like" drinks that Starbucks serves.
There are several shops in Athens.
I have visited the two central shops ( Omonia Square & Korai Square) and one in the suburbs ( Agia Paraskevi).
The coffee and the music are exactly the same everywhere.
Finally....a warning! Avoid the toilets of the two central shops! They are really dirty....
