When the CVS renovations are completed in the late fall, C'est Bon will expand into the former site of the Army Navy store, which is currently occupied by CVS.
"We are definitely going to increase the size of the store," said C'est Bon's manager.
The new summer developments are the most recent in a line of announced closings and departures. In June, Sage's grocery store left its Brattle Street location.
Owners of Grafton Street announced recently that they would have to leave their 1280 Mass. Ave. location by next June to allow for the expansion of Cambridgeport Bank.
"The whole Square is changing, so you have to go with the flow," the C'est Bon manager said.
