But you do not have to worry about this detail (and many other details that come with organizing a dessert table) because we, at Sweet Events, will guide you in planning for your cake, and your dessert table. We also can order your custom cake from our experienced bakers who we have established working relationships with here in the Bay Area, and therefore can get good prices.
Below is a "Cake Portions Serving Chart" to help you approximate the cake size to order based on the number of guests at your event. Just double click on the file below:
