Bars in Arequipa & Cusco, Peru
In Cusco check out:
Museo De Pisco on Calle Ruinas. They specialise in excellent pisco cocktails and all pisco drinks and also do very tasty tapas. (Pisco is Peru's national drink)
Other places for great cocktails are Marcelo Batata - they have a nice rooftop terrace with a good view of Cusco's cathedral: http://bit.ly/11rHL9H
and Fallen Angel: http://bit.ly/ZabilF
Happy pisco tasting!
