You'll get one of the other customers in the shot, so taking photos of the restaurant is prohibited.
他のお客様 = other customers / other diners
写る / 撮影 = to shoot / to take a picture of
から = because / so
店内全体の = the entire inside of the shop -> the (whole) interior of the restaurant
禁止 = forbidden / prohibited
料理が大丈夫なら、
You can take pictures of the food, but not of the interior (of the restaurant).
の言い方も使えます。
You may take photos of the food but not the restaurant!
We don't allow photos of the restaurant but you can take photos of your food!
Many restaurants will allow you to take photos if the place is empty but if they have clients/diners/customers inside, then it is prohibited/banned. They don't have any problems with you taking pictures of your food because they do not want you to take any pictures of other diners.
"prohibited/banned" - not allowed
"diners" - other people eating at the restaurant
"We don't allow you to take photos of the interior of our restaurant, as you may take a photo of a customer by mistake." "However, we do allow you to take photos of the food."
To "allow" or "not allow" ("don't"), gives a clear message to the customer of what type of behavior you expect in your restaurant. You back this up by giving them the reason why you "don't allow" it ("as you may take a photo of a customer by mistake"). By using "by mistake," you are telling them you understand it wouldn't be their fault if this happened, especially if they didn't know the rules on taking photos beforehand. You finish on a positive note by informing them what you do "allow" in your restaurant ("However, we do allow you to take photos of the food"). There could be no misunderstanding between you and the customer, if you said it like this.
"allow" または "(do) not allow" を使うと、レストランで規則について明確に伝えることができます。
この後、なぜそれができないのか理由を説明します（"as you may take a photo of a customer by mistake" ＝ 他のお客さんが写真に写る可能性があるから）。
"by mistake" は、「仮にこれが起きたとしても（特にそのルールを事前に知らなかった場合）お客さんには非はない」という話し手の気持ちを表します。
最後は肯定的に、レストランでできることを伝えています（"However, we do allow you to take photos of the food" ＝ ただ、料理の写真を撮ることはできます）。
このように言えば、お客さんとの間に誤解が生まれることはないでしょう。

Our policy strictly limits photography to pictures of the food only as to respect the privacy of our patrons.
Please limit your photos to pictures of your food in order to avoid taking pictures of our guests.
1.
Mentioning that the request is policy can help to avoid causing the visitor of the restaurant to assume that he/she is being singled out. A patron is a word that is used for customers in a restaurant or hospitality service and is used to show the value of and respect for the customers.
2.
It is also very respectful to refer to a restaurant customer as a guest. Using the word "limit" is a good way to express to the person taking the photos that he/she still may take photos, but there are guidelines for what is acceptable.
You can take photos of the restauarant but please avoid snapping any of the customers
You work at a restaurant. When a customer is trying to take a photo of the interior of the restaurant, you want to tell them that they can take photos of the food, but not the interior because they might get another customer in the shot. The above suggestion deals with that point.
