Probably don't need to learn how to speak it, but good to know if someone is asking you. "Is that all? How about tea, dessert or an embarrassing birthday celebration for you?"
French: Ce sera tout?
Spanish: ¿Eso es todo?
Arabic: هل هذا كل شيء؟
Mandarin: 就这些了吗 [Pinyin: Jiù zhè xiē le mă?]*
English: Is that all?
