My best friend is organizing a gender reveal party for close friends and family members at a convenient location for all people invited to announce the sex of our first child. We have a small apartment that is not suitable for a group of people larger than 5, so we thought we could do it at a restaurant. I think that most of my twenty-something friends will understand that this is a pay for yourself meal, as we are not accepting gifts. We are sending an evite and are trying to decide the best wording, so that older family members and more traditional people, understand that in this case, they will be paying for themselves, without being offended. Please Help!!
