Hey- for some reason it would not let me reply to your question about how much the vendors were.
Deweys-My cake was 4 tier with chocolate, white, red velvet and pumpkin spice with cream cheese icing. The total was $490 which included delivery and a silver cake stand. Not sure if I have pics of the cake on my camera but if I do I will post.
Salem Kitchen-It was about $4300. We had a heavy app buffet. We did cheese/fruit, ham biscuits, spanikopita, brisket toastadas, beef tenderloin, a pasta station, crab cakes, pesto cherry tomatoes and chicken slovakia skewers. The price included disposable plates and tea/lemonade/water and coffee.
