Before Yom Kippur I posted an article pertaining to the kashrus of a sukka found in a restaurant/catering facility. I explained one needs to determine if a hashgacha covers the sukka as well, which is not always the case even though one might expect it to be so.
The OU in Israel has clarified that a sukka in an establishment under its hashgacha is covered by the hechsher only if one sees a special teudat kashrus from the OU stating clearly it assumes responsibility for the sukka.
That means even if there is an OU hechsher for a restaurant, you must see a second one covering the kashrus of the sukka. If the latter is absent, the hashgacha assumes no responsibility for the sukka.
