Having worked so many weddings and events over the years as a photographer, I offer the following recommendations for service providers.
Most facilities will require you to use their caterer, but for home-based events and open source facilities, the following caterers are recommended.
The parties in my recommendations list have no affiliation with me; I have only worked with them as peers. I cannot guarantee your success with their services. Remember that the event success is a two-way street; these service providers are only part of the equation for your event.
