Answer: Enjoy your tea and hope you like it.
If you have preferences for guests:
Ask: What do you prefer? Coffee or tea? (if coffee, you should ask: milk & sugar? or black?)

你指的是中國茶嗎?

如問他飲唔飲. 當然是:

Would you like some Chinese tea?
Would you like a cup of tea?

要加 "some" 或 "a cup of", 因為要有量詞

假如是想給奶茶, 就要問埋 奶+糖 了:

Would you like some tea?
Milk or sugar?

至於 "Enjoy your tea!" , 你喜歡便在呈上熱茶一杯時說, 因這個不是問人飲不飲, 而是呈上後叫人享受, 同埋不需要加 "please", 因為你不是叫人幫忙, 相反是別人要你幫忙沖茶, 所以是應由他說. 這樣說已經夠禮貌了

1.
a. If you have diferent kinds of drink to offer.
Would you like something to drink?
b. If you only have chinese tea and water.
Would you like a cup of chinese tea or water?

2. After you have served the drink, you can say "Please let me know if you need anything."
