The long distance buses in Argentina are great, big, fast and comfortable but there are some difference from company to company. From all the companies I?ve used I think Andesmar is the best (but the most expensive also).
The bus to Buenos Aires was a big surprise as they provided us with a meal in the afternoon and breakfast in the morning. We had a movie in the screen and a bingo game! They gave us some little papers with numbers and we started playing until one of us shouted out ?bingo?!! I don?t know what was the gift from Andesmar (I think a wine bottle) but it was very funny.
The big bus station of Mendoza is called Terminal del Sol(tell the taxi driver ?terminal de omnibus?) and serves many routes all over the country and it?s located in the city center. There are offices of all the bus companies that have routes to Mendoza and also some tourist offices with tours around Mendoza etc. Some small stores will provide you with water and food for the journey (although some companies like Andesmar provide this kind of stuff during the journey!).
I also found an office of Andesmar in the city center (there is one inside the bus terminal of course) where I booked my bus tickets in advance, for exable one from Santa Fe to Puerto Iguazu. The English speaking stuff was very helpful. Address:Las Heras 699 tel:0261-4253108
If you drive from Bs.As by car you?ll need 10 hours for the trip
