It’s the summer of the sequel and some of Boston’s culinary superstars are expanding their empires with the follow-up restaurants all over the city, and in some cases, well beyond. The blockbuster summer season started with Ken Oringer opening his first Fenway venture, La Verdad, and almost simultaneously, getting KO Prime up and running at the Nine Zero Hotel. From the team behind blu at the Sports Club LA, comes Rocca – chef Tom Fosnot’s ode to Ligurian fare – in the deep South End. In the sneak preview department: Memorial Day marks the opening of chef Chris Parsons’s Martha’s Vineyard expansion – the culinary force behind Winchester’s Catch, opens Catch at the Terrace at The Charlotte Inn in Edgartown. In a couple weeks, John Moore, owner of the Navy Yard Bistro, will open the Downtown Bistro & Wine Bar in Lynn, in the space that the Oxford Street Grill once called home. Chef Geoff Gardner takes his Sel de la Terre show on the road, bringing his Provencal goodies to hungry suburbanites in Natick come early September. Gaslight, the long awaited and much anticipated new endeavor from chef Seth Woods and the folks behind the Aquitaine Group (Armani Café, Aquitaine, Aquitaine Bis, Metropolis Café and Union Bar and Grille) is also slated to open in September on Harrison Avenue in the South End. Check back for more information about other coming attractions including Stix from the team at 33 Restaurant & Lounge, Oliver’s from Todd English and company, Sofra from Oleana’s Ana Sortun and Maureen Kilpatrick.
