A rep from Ostra, the newest restaurant from the Columbus Hospitality Group (Mistral, Teatro, Sorellina, Mooo and L’Andana), tells me that they're now looking at a late November opening date. Ostra replaces Avila at One Charles St. The restaurant specializes in Mediterranean-inspired seafood, with chef/owner Jamie Mammano and executive chef Mitchell Randall (also of Mistral) at the helm. There's also a piano bar. A piano bar in the Theatre District that isn't at Jacob Wirth? Swanky!
