Is this a good idea?

My husband and i are celebrating our first year anniversary today. It's really on labor day but places are closed. So today we are going out. I am 19 weeks pregnant as well. I have the envelope for my baby's gender reveal. Since we didn't want to find out at the doctors office.

Since we are going to a fancy restaurant, i was thinking of doing a reveal for us by getting a waiter to bring us "dessert" when really shes bringing the ultrasound picture plus a baby's bottle and a onesie for either a boy or girl on a plate.

Do you think this is a good idea ?
