Perennially popular, guidebook-endorsed breakfast spot Mama’s in North Beach is finally going to do something about that line. The Chronicle hinted today that they’re looking at expanding to a second location in the neighborhood, possibly at the former Piazza Market space at Vallejo and Columbus. And Mama’s manager/partner Felicia Sanchez-McDonnell confirms for Grub Street that the family is focused on that 7,000-square-foot space, despite some permitting issues. “We know it has a restrictive conditional use permit, but we’re cautiously optimistic about the possibilities,” she says. “We’d love to have the space to alleviate the line and take care of the neighborhood folks. We also have some plans to use the additional space to have a specialty shop with take-away items and some of our house-baked treats.” [Chron]
