June July will be in BA


From reading quite a bit of info from this site, I am planning to get around and really see this city. Sounds as though there are many real characters in BA. I am a coast rat from the Santa Cruz area of California. What coffee shops or bars would anyone recommend to visit and meet some expatriates? Also in all the info I have gathered not once have I read anything about motorcycles. Are there any in Argentina? In Europe they are #1 form of transportation around cities. Looks also like the down jacket comes along too. Thanks.
