There was one vendor there who I would love to do business with - Christina Michaels. They are cake artists who make beautiful styrofoam cakes covered in icing and sugar flowers that you use as a display cake during your reception (you keep the top of the cake to display for years). They provide sheet cakes for the hall to cut up and serve immediately after you cut the additional small edible cake they give you. You don't have to wait between the time you do the 'cutting the cake' ritual and the time the cake is actually served. (You also don't get all the germs from the fake display cake that people were leaning close to take pictures of.) We tasted one of their cakes - wow - it was amazing. This guy takes pride in his work.
*Edited to change the post into a solely positive one for only one single vendor (you girls who FM'd me read the other comments originally written).
