I suppose you have made a mistake in Pinyin~~~not "dedao",but"didao",so the translation is "你想要地道的咖啡嘛？"

hi,i think that is 你想要得到的咖啡吗？ but this sentence sounds strange.

你好 Martini, I hope I can help you with your question: 你想要得到的咖啡吗? nǐ xiǎng yāo dédào de kāfēi ma nǐ = 你 = you xiǎng = 想 = like yāo = 要 = demand, want, ask for dédào = 得到 = to get de = 的 = a chinese grammar partikel kāfēi = 咖啡 = coffee ma = 吗 = the partikel “ma” is the chinese symbol for a questionmark (ma = ?) Word to word translation: You like want get coffee ma Translation: Would you like to have a coffee? Greetings from germany, Kathrin

你想要得到的咖啡吗

Hello Martini， 你想要得到的咖啡吗？ "Would you like to have a (some) coffee?"
