One of the most anticipated local restaurant openings of 2015 is upon us as Townsman (120 Kingston St., 617-993-0750, townsmanboston.com) has finally cut the ribbon on its downtown digs. So what’s all the hubbub about? First, the eatery is committed to the increasingly popular concepts of sustainable and seasonal cuisine, featuring fresh local seafood along with house-made charcuterie. Second, it is the first Boston restaurant for chef/owner and native son Matt Jennings, who had been nominated multiple times by the James Beard Foundation for Best Chef: Northeast during his tenure at his acclaimed Providence, R.I. restaurant Farmstead. Fostering a friendly atmosphere highlighted by its lively counter service, Townsman looks to be one homecoming that was well worth the wait.
