The lunch options in Wainscott got more interesting this week with the opening of the SoFo Sandwich Co. at the long-empty spot that was previously home to Breadzilla, popular for its baked goods and takeout breakfast and lunch menu. The new shop is by Peter Ambrose, a catering chef whose food many will be familiar with from Love Bites, a fund-raiser for Katy’s Courage, among others.
