I recently rented Rachel Getting Married and loved the idea of the bride and groom assisting in the serving of the meal at the reception. As much as I love the idea of a party 'all about me', I prefer in actuality, hosting an event where my hands 'get dirty' so to speak.
I think a wedding that feels more like a huge family dinner would be preferable to a highly structured, catered event.
I image a reception that has food made by the bride, groom, and their friends and family. The fathers and uncles standing around the BBQ and a group of close friends act as the servers.
I would give handmade aprons for friends and family that help cater and serve dinner.
It still bothers me that when ever I look up ideas for hosting and catering your own wedding that exceeds 50 guests, I usually find "Don't do it." advice. Hopefully that is changing.
