Ouzo is a typical Greek alcoholic drink.
Every shop selling Greek foods should have it, I guess.
When every country has things for which it is known, then it's Athen, Ouzo and Zaziki and Olives as typical Greek products for me. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
