外卖用英文怎么说？

可以用to go
意思是:To be taken out, as restaurant food or drink:
可带出去的：可带出去，如餐馆里的食品或饮料：
例句:coffee and doughnuts to go.
可带出去的咖啡和当纳圈
另外还有其他翻译:1. take-out; takeout; [British] take-away (of or involving food to be taken and eaten off the premises)
2. takeout; takeout food (food that is intended to be eaten off of the premises)
3. [Informal] takeout (a store, restaurant, or counter specializing in preparing food meant to be carried out for consumption elsewhere)
希望对你有帮助~

take-away food 意为可带走食物，

我认为也符合外卖的意思。

take out
order

take out

order
