SARAH WAGNER returned to Barresi’s about a year ago. When the Barresis decided to sell, she stepped up. Wagner remembers a day years ago when she was still a young employee, studying to become a massage therapist. One of the chefs didn’t show: “Odessa looked around and said, ‘You don’t have a station and you’ve been here for four years: Why don’t you put together the salads?’ ” That was the beginning of a career. “It’s going to be the same place with the same recipes, served by the same staff,” Sarah says, “but we’ll be revving up the marketing and doing charity benefits.” Barresi’s has been frequented by diners who knew Sal and Odessa for years, and Wagner’s certain they’ll still enjoy it — but she plans to extend its appeal to her own generation. Sounds like a new star is rising in the dining firmament!
