Out and about downtown this weekend, or planning to head to the Esplanade on the Fourth? Make a pit stop at The Merchant for $1 dollars from Friday, June 30th through Wednesday, July 4th. They’ve got seafood aplenty if oysters aren’t your thing like spiced swordfish tacos, pan seared dayboat scallops and grilled sea trout, among other offerings on the American-leaning menu (try the buffalo cauliflower or cider braised pork shank). For those who need something to drink to get through the heat, there are newly unveiled espresso martinis on tap at the bar. Stop by the Franklin Street spot, or call 617.482-.6060 to make a reservation.
