A friend of mine has a restaurant and invited me and guests to attend a party that they're having. The rest. will be closed and it will be just friends but I'm not sure what to do as far bringing something. Usually, if I'm invited somewhere I'll bring wine / drinks or cook something (usually dessert) but I'm not sure what to do in this case since he owns a restaurant. Any suggestions? It seems to be a party for just the employees and the family. What would the appropriate thing be to do?
