Supposedly, the third time’s the charm. In the case of the South End’s go-to Franklin Café (278 Shawmut Avenue, Boston, 617.350.0010), we think chef/owner David Dubois hit the mark the first time. Now he’s using that success to propel a third Franklin (the second one’s in Gloucester) into the Allele condo complex in South Boston. The new restaurant, slated for a mid-November opening, will be called Franklin-Southie (152 Dorchester Avenue, South Boston) and will feature a small outdoor seating area, weekend brunch, and late-night plates served until 1:30 a.m. Chef Brian Reyelt is on board, but don’t fret: he’ll continue in the South End kitchen, too. And while the menu is still in the works, Dubois assures us that we’ll see some old favorites from the original Franklin list.
