There are several popular bars where expats can find friendly faces. In Barrio Norte, there is Casa Bar, which is owned by Americans, serves cold beer and spicy hot wings, and streams college football, basketball, NFL, and NBA games. Club Aráoz, on Aráoz 2424, is also a popular place with young Americans, with hip hop music and reggeaton playing later on in the evenings. Meanwhile, The Gibraltar is a quintessential English pub in San Telmo (Perú 895); it also has well-priced food specials if you need to satisfy a craving for fish and chips or some Thai curry.
In Palermo, the bars and clubs around Plaza Serrano always attract an international crowd. The expat-owned Sugar (Costa Rica 4619) is a chic bar with happy hour specials that run until midnight. Among the popular boliches (and there are many), Kika(Honduras 5339) and Niceto Club (Niceto Vega 5510) have outstanding sessions with DJs who spin and sample the latest cutting-edge tracks while a hip young crowd brings the groove. Next door over in Almagro, Amerika (Gascón 1040) has good vibes that make it one of the top choices for gay and lesbian expats. And every Monday, La Bomba del Tiempo, a can’t-miss drum ensemble, performs at Ciudad Cultural Konex, a former factory that’s been converted into an arts center (Sarmiento 3131).
If you’re looking for an expat group, there are several in the city. Meetup.com is a great source with a few groups listed in Buenos Aires. A resource for improving your Spanish is Spanglish Exchange, which brings locals and foreigners together for conversation practice. New events are organized weekly, with alerts sent out to anyone who signs up via their website. Good Morning BA is another expat group that organizes events, and the BA Expats forum also advertises meetups for dinner and drinks on a regular basis.
