哪位大侠教几句餐厅英语啊？

请问需要些什么: What would you like?
您的餐好了: Your meal is ready
请慢用: Please enjoy your meal
欢迎下次光临: 洋人不这样说的，不过走的时候可以说Have a nice day
一共是**钱: It's ** dollars/yuan in total
是带走还是在这吃？: Have here or take away?

What can I do for you?
Here is your meal. Please enjoy it.
Welcome back.
The total amount is ...
Do you wanna have it here or take-away?
以上是你例举的。
还有
May I recommend you to some...请让我为你推荐XX食品
The drink is hot, be careful! 热饮，当心！

呵呵，这我比较在行，在新加坡经常打工当得就是服务生。
他们一般不说需要什么，都说Can I help you.
您的餐好了，请慢用，你可以直接说Enjoy the meal.
欢迎下次光临也没听他们说过，不过要说的话大概就是expect your next coming.一共多钱，total is....别忘说完说THANK U
带走还是吃，having here or take away?

客人来的时候你可以说(how) can I help you?或者is there anything that i can help?这几种说法都对。

您的餐好了,请慢用：your order is ready,enjoy！ 外国人不说‘请慢用’，可以直接说enjoy，而大多数直接说thank you

欢迎下次光临：直接用‘see you later’

一共***钱：‘that's ***’或者‘all together is ***’
