Plenty of Boston restaurants serve fresh seafood, but Row 34 has emerged as one of the best. The restaurant is at the vanguard of the Seaport District’s renaissance, and represents what’s both new and classic about this hot neighborhood. It has a short menu—dominated by oysters, crudo, and ceviche, and including a handful of fish dishes and one or two chicken and beef choices—as well as a long list of wine options and an upscale industrial vibe.
