NORTH ADAMS — The key to a good sandwich: the bread.

That’s according to Berkshire chef Xavier Jones, who will soon be serving up Philly cheesesteaks in the Berkshires once again, and on bread imported from Philadelphia.

In late April, Jones and two other co-owners, Warren Dews Jr. and Dully Saimbert, are opening BiggDaddy’s Philly Steak House on the Massachusetts Museum of Contemporary Art’s campus in a space that was occupied by A-OK Barbecue until it closed last year.
