While in Buenos Aires we ate at Don Julio's steakhouse, it is ranked as the number one steakhouse in South America, YES it was very good. After leaving Buenos Aires we took an 18 hour bus ride to Mendoza Argentina. I enjoyed this city better than any other in South America. We took a winery tour around Mendoza, we visited four different wineries testing 4 wines at each stop, at the end they tasted the same. (I wonder why??) There are over 1,000 wineries in Mendoza, they love their wine.
Another day we toured the Andes mountain range which runs all through South America, the best stop on this tour was the starting point for hikers going to Aconcagua (the highest mountain in the Andes).
Most of the time in Mendoza we took walking tours seeing all the cafes and bars.
