We followed up a recent trip to the lovely Lyman Allyn Museum in New London with a trip to the Oyster Club, 13 Water Street, Mystic. And, of course, we had to try the oysters. In this case, we tried a half dozen of the roasted oysters served with a brown butter sauce. The rest of the dinner — including a burger, the chowder, housemade pasta topped with a delicious ragu, and some fish — also was good. But the oysters? So good we’d go back for just that. The seasonal menu is adjusted daily to make best use of what’s fresh at the market, so visit www.oysterclubct.com/menus to find out what’s available.
