China, Glassware, and Flatware
If you are going to have a dinner party at a restaurant after the wedding, most likely the restaurant will have the china, glassware and flatware. But they are pretty basic, so if you want to add some specility to them, you might think about the overall style. For instance, if the reception is hosted outdoor, flatware with translucent plastic handles are good enough. Bone or white china edged in silver or gold is great to wedding reception. The choice of glassware depends on what you are going to serve. Of course, you can use all-purpose wineglasses, but if you will serve a margarita or martini, you might want to have some special glassware. The choice of flatware should match the style of china and glassware. If you want to have a modern look, streamlined flatware is good, or if you prefer tranditional way, you can go with ornate flatware.
