I go into a coffee shop pretty much every day. I love coffee. Probably drink too much but I usually switch to decaf after lunch. Anyway, I go in and see this latte and espresso but I'm always kind of afraid to order this stuff. I even saw a sign in a coffee shop once that said: "Espresso- If you don't know what it is, you won't like it". So my question is - what is a latte and espresso? I want to know if I'm missing out on something.
