Working Dinner: (N) - something of a redundant term since most if not all meals take place in groups ("dates" excepted, on occasion), and most if not all of these meals turn into shop talk, brainstorming, and business planning. Thus, there are official "working dinners" between new or proposed partners, "working dinners" in which pre-existing partnerships hash out plans while enjoying food and drink, and "working dinners" in which old partners inadvertently invent or hash out plans without that being a stated intention of a seemingly social or biological function such as dining.
