2. To provide a huge range or amount of food and drink to one; to provide one with a feast. The bosses said they're planning on regaling us all with a huge company dinner as a way of saying thank you for all our hard work over the last few years. The Andersons always make a point of regaling the neighborhood with a massive spread of food at the end of each summer.
