The Sea Hag Restaurant and Bar

The Sea Hag on Mount Auburn Street serves seafood with a Portuguese streak running through the menu. Shrimp Mozambique comes with garlic, saffron, rice and fries, while Portuguese kale soup includes linguiça. A cauliflower version of Mozambique gives the table another way to order the dish. Those are good places to start if you want something beyond the familiar fish and chips.

There are fish tacos and a crispy shrimp burger too, alongside steak frites and fried chicken. That range makes the Harvard Square restaurant workable for a group whose seafood enthusiasm varies. Come for a meal and a drink, and check the current menu before planning around a particular special. Its address is 49 Mount Auburn Street, a short walk from the square.
