0 a meal in the middle of the day that consists of drinks, usually alcoholic drinks, and no food, or not much food --
I was in a bar having a liquid lunch.
Just a straight-forward, classic room that has deal-makers doing liquid lunches, handbag designers with few alternatives in the area, and tourists who dress like grown-ups.
Drank to excess, came to the office hungover, left for liquid lunches.
