Yes, guests at a wedding typically eat the wedding cake. The cutting and serving of the wedding cake is a traditional and symbolic part of the reception. After the cake-cutting ceremony, the cake is usually taken to the kitchen or a designated area where it is sliced and served to the guests. The wedding cake is often included as a dessert option during the reception, and guests are expected to enjoy a slice of cake as part of the celebration.
However, it's worth noting that individual preferences and dietary restrictions can vary among guests. Some people may choose not to have a slice of cake due to personal preferences, allergies, or dietary restrictions. In such cases, alternative dessert options are often provided to accommodate various tastes and needs.
Ultimately, whether guests eat the wedding cake or not depends on their personal choices and circumstances, but it is a customary and expected part of the wedding reception.
