This means: Do you have coffee?
This is a VERY important phrase to know. Here are some other Spanish phrases we have learned or are learning.
¿Dónde está el baño? (Where is the bathroom?)
No entiendo! (I don't understand.)
Yo quiero agua de botella, por favor. (I want BOTTLED water, please.)
So at the point, we can get coffee, water, use the bathroom and let others know we don't understand anything else. We are making some progress.
