Alamo bar on Uruguay street just off Santa Fe, I watched a game there last night. Nothing special but they have lots of tvs and I hear most Sundays get a good crowd
I was at Downtown Matthias in Belgrano the other night and they were playing the college bowl games. If we get a group together, I can get a local friend to call some places ahead of time and ask if whichever place will have the games on for us.
