There are really only three reasons to visit Quincy: you're a presidential buff, you took a job at State Street, or, well...okay so there're really only two reasons to visit Quincy. Finally offering you a third, Port 305.
A second MB offering from the owner of neighboring Siros, P305's a casual Southern-comfort-fare-meets-classic-New-England-seafood waterfront hybrid located in the renovated 130-seat former Amelia's and Skyline spot, now outfitted with a private upstairs dining room offering a scenic harbor/skyline view, a 30-table outdoor patio overlooking the marina, and a 365-degree bar, which Shaun White deems wayyy too easy to drink at. Burly Dixie farm grub includes a fried 9oz Statler chicken served with its own gravy'd mashed potatoes/corn on the cob; Kentucky bourbon marinated steak tips w/ pancetta BBQ baked beans; St. Louis ribs plated w/ Asian-style 'slaw and sweet grilled cornbread; and a horseradish cream'd 12oz rib eye grilled w/ tobacco onion strings, because just eating regular fried onions isn't nearly unhealthy enough. There's also seafood deliciousness like fried cornmeal whole belly clams served w/ tartar sauce and cole slaw; pan seared salmon with a citrus soy glaze; and a toasted panko crumb-encrusted creamy mozzarella/Parm mac and cheese with white truffle oil and lobster meat that's handpicked, due to its nickname Acie (C)law.
For afterwork drinks on the deck, P305's brings the following-day pain with a solid selection of beer/wine and festive summertime cocktails like pitchers of Tropical Island Ice Tea (gin, tequila, coconut rum, and Coke), and the gin, cherry brandy, and grenadine'd Singapore Sling -- repping a country that you have more than three reasons to visit, though all of them involve caning.
