we went to an incredible tango show... cafe tortoni - on avenida de mayo (the big street) which is pretty famous too. if you're there on a sunday there is a market in San Telmo which sells loads of brilliant antiques and is a real chance to see some proper portenos. Also, you can buy some silver which apparently argentina is famous for. visit the casa rosa, the building from which Peron and Evita did all their rousing speeches. the steak really is out of this world - everyone goes on about it but once you've tried it you'll be one of those people too... am trying to think of everything we did!! a visit over to uruguay is a nice idea - although instead of sailing to montevideo, I'd go to Colonia de Sacremento. Montevideo is much like a less good Buenos Aires, Colonia is something else. I think it's a world heritage site, it's really beautiful and if you go there on a clear day it'll just take your breath away. what else...? have a lomo completo - it's a brilliant steak sandwich. and a submarino - a glass of hot milk which you dissolve chocolate in (my description does not do it justice. having these on a cold day in ba is one of my happiest memories!!) la boca is lovely too, but prepare to be hassled by the locals - they are desperate for you to visit their shop and their tango show! finally, if you can take in a football game. the atmosphere is unsurpassed!
