A friend told me once: 'Never sacrifice a friendship for a kiss'. And I think there's a lot of truth in that. The thing is that in Argentina people kiss each other a lot, even with this swine flu thing. So I guess you do get to kiss your friends and keep them, too. That same friend tried to order a submarino thinking it was a sandwich.
I think it can be a bit difficult to know how to order coffee here. Sometimes the names are different and some other times the names are the same but the drink is different. So here's a quick list of different coffee drinks. I'm sure I'm forgetting one or two, but well... that's what you get for kissing friends.
cafe: small espresso
cortado: small espresso with a couple of drops of steamed milk
cortado jarrito: cortado on a larger cup
lagrima: steamed milk and a couple of drops of coffee, served on a small cup
lagrima jarrito: lagrima on a bigger cup
cafe con leche: espresso shot with steamed milk (pretty similar to a european capuccino)
capuccino: espresso shot with steamed milk, served on a big glass dusted with cocoa powder and cinnamon
submarino: steamed milk served with a bar of dark chocolate (not a sandwich!)
