Can 「持ち込んだ食品を飲食するのは禁止である。」be simplified for a notification board?


I want to write a notification board saying

> Consuming outside food and drink is not allowed.

My attempt is as follows, but I think it can be simplified.

> 持ち込んだ食品を飲食するのは禁止である。

# Update

Bring outside food and drink is fine as long as they are not consumed. This
exemption might be useful for those who come to the restaurant after shopping.




To the Update: Even to mean that, people usually use the phrases like:

>   * 飲食物の持ち込み*禁止
>   * 飲食物の持ち込みお断り
>   * 飲食物の持ち込みはお断りしております。(← politer)
>   * 飲食物の持ち込みはご遠慮｛ください。/ いただいております。/ 願います。｝(← politer)
>

etc...

(You can use these phrases for that purpose because the word 飲食物 is used here;
you'd use 食品 or 食料品, not 飲食物, to mean _any_ foods / food products, as in:
「食品/食料品の持ち込み禁止」"Bringing in any groceries/foods/food products is not allowed")

But if you want to more clearly say or emphasize that bringing in food and
drinks is fine as long as they are not consumed, I think you could write:

>   * お持ち込みされたもののご飲食はご遠慮｛ください。/ いただいております。｝
>   * 店外からお持ち込みの物の飲食はご遠慮｛ください。/ いただいております。｝
>   * 他店にてご購入の商品の飲食はご遠慮｛ください。/ いただいております。｝
>

*You could spell it as 持ち込み, 持込み or 持込. 




How about **飲食物持込禁止**? It is more like for a notification board. (e.g. see
<http://peragami.com/?p=662> )

Generally, if you want to do this kind of simplification, you can omit
particles like の/を, a trivial verb like 〜である, and some 送り仮名.

The sample above can be reduced from 飲食物 **の** 持込 **は** 禁止 **である** or 飲食物
**の** 持込 **を** 禁止 **する**.

Although a notion of consuming is also omitted, one can understand it
correctly.
