Vivacious pop-up supper club, Bon Ami, is celebrating the start of autumn with a set of squash-themed dinners. Known for its intimate and enthralling Monday nights, Bon Ami develops menus for its invite-only dinners using seasonal ingredients available from its farm partners. For select dinners in October, this means diners can enjoy unique and thrilling preparations of various local squashes, a staple of fall produce in New England.
