Your caterer should certainly be able to give you a good idea of what is available in your desired price range. Obviously, a formal meal with tuxedoed servers would be more expensive than a simple buffet. Linen tablecloths and fine china would cost more to use than plastic or disposable alternatives. Be clear on exactly what you are paying for, line by line and find out whether items like tax or gratuity are included on your final estimate. Ask to see a portfolio.
Caterers are typically responsible for both the food and the table settings.
They will dress the tables as you see fit. It is a good idea to look through the caterer s portfolio for ideas and assurance that you will be pleased with the work. If you want to have special floral arrangements, you will need to work out such details with a florist and let your caterer know what you plan to do. The same goes for the cake. However, it is important to coordinate the arrival of the cake at the reception with the catering staff so that the appropriate table will be dressed and ready for the presentation.
