The answers from ivanhuang911 are all right,except that we don't say "have a coffee".We say "have a drink",but with coffee it's just "have coffee" or "have a cup of coffee".
Also,we don't say "treat you to a cup of coffee" because coffee is something little.I personally don't consider coffee to be big enough to be a "treat".
1.I will buy you a drink/ I will get you a drink.(if you use "offer",it sounds formal and a little strange)
2.I will buy you some beverage/ I will get you some beverage.
3.I would like to invite you to have a cup of coffee with me.(the direct translation sounds very formal though)
I want you to have coffee with me.(this is the informal way of saying it) The answers from ivanhuang911 are all right,except that we don't say "have a coffee".We say "have a drink",but with coffee it's just "have coffee" or "have a cup of coffee".
