1. Americano. It's just a watered down espresso but it seems like you're getting better value. Plus it's not gone in moments
2. Espresso. Gone in a moment but when done right it's still very good.
3. Café au lait/latte. Excellent in the morning
4. Cappucino. Coffee with foam on top. OK if the coffee is good but you're paying a lot more for extra foam and less coffee. Then again, the foam tends to keep it warm. The most popular kind in many places.
5. Foamy, milky, creamy, flavoured gunk.
