Planar Restaurant doesn't have an official halal certification that we could find. However, it is mentioned on a third-party booking website that they offer halal options. Since they also have pork and alcohol on the menu, we recommend speaking directly with the restaurant staff to understand how they prepare their halal dishes.

Yes, Planar Restaurant has a full bar and serves a wide range of alcoholic beverages. Their menu also includes several dishes with pork, bacon, and prosciutto, so it's a mixed kitchen environment.

We couldn't find any specific information about whether the meat is hand-slaughtered (zabihah). For details on their meat suppliers and slaughter methods, it would be best to ask the restaurant directly.

We did not find any information about a prayer room within the restaurant itself. Being located at the International Convention Centre (ICC) Sydney, there may be multi-faith prayer rooms available within the convention centre. We recommend checking with the ICC guest services for the nearest facility.

Planar is a spacious restaurant with outdoor seating and is known to be family-friendly. While they can likely accommodate large groups, given that it's a mixed kitchen serving alcohol and pork, it's important to discuss your group's dietary needs clearly when booking to ensure they can cater to you safely.
