there's a hidden terrace in tirso de molina. it's called the casa de granada. can't remember the name of the street, it's the one that goes up to plaza benavente & ideal yelmo cinema. you have to ring the bell on 5th floor and go up in lift
cheap too - a tercio of alhambra beer is 1.10€
busy on sunday afternoons, you might be lucky to get a seat outside
