请尽情享用（有时候我也会说：this is your meal, please enjoy it.）

Thank you for coming!
谢谢光临

Would you like to have anything to drink first?

Would you like to have red or white wine?

Have you finished? /May I remove this for you?
请问您吃完了吗？/我可以帮您把这个（盘子，碟子之类的）撤了吗？
通常情况下，如果是西餐客人吃完后会把刀叉并拢放在碟子中间，如果没有吃完则分左右搭放在碟子上，不过保险起见还是问一下好。我就碰到过把刀叉放在中间还没有吃完
