The restaurant openings in the Seaport just keep coming. The latest addition? Savr, a two-story, 300-seat bistro attached to the luxury St. Regis condos at 150 Seaport Boulevard, debuting at 4 p.m. today. According to a rep for the restaurant, it’s open to the public (although there is private access for residents) and includes a waterfront deck overlooking the Boston Harbor. Savr’s executive chef Danny Levesque, a steakhouse veteran who previously worked at Abe & Louie’s and Davio’s, is overseeing a menu focused on pasta, seafood, and wood-grilled steaks.
