The restaurant is celebrating its anniversary. From now on till the end of this year, we don't have to give tip when we have buffet dinner there from 5:50 to 9:00, from Monday to Thursday.
I try to say the above to an American pastor, who is very kind and enthusiastic, because I'd like to treat him and his family an all-you-can-eat buffet before this coming Christmas. If there is anything wrong, feel free to let me know. Thanks.
Thanks, Mike, for the helpful reply.

I would be more comfortable adding a "to": I'd like to treat him and his family to an all-you-can-eat buffet before this coming Christmas."
