How are you serving your desert/cake? Are you serving it after dinner while everyone is still seated or are you having a desert bar so that people can pick/choose what they want to eat?
I'd really like to have more than one flavor of cake at the wedding, but we also have a couple indian deserts for people to try too. I'm wondering if we should serve them all to everyone after dinner or do a desert bar so that people can decide themselves what they want to eat...
