Portland's Ebb and Flow Chef/Co-Owner Eyes New Restaurant Concept

Their business is a half year old, their baby only a month old, and it appears Ebb and Flow chef/co-owner William D'Auvray and his partner Melissa Santos (who is also heavily involved with Ebb and Flow's front of house) are ready to welcome yet a third newborn into the world: namely, another restaurant. Santos, who keeps up a steady stream of entertaining chatter on her Twitter feed, dropped the hint yesterday:

offer was accepted. looks like we have another space to do the restaurant concept William has been planning since 2011.

She declined to comment beyond that for now. What do you think the concept could be? What would you like it to be?
