From the Hua family, which owns the Vietnamese soupery Pho Long a few doors west in U. City’s Jeffrey Plaza strip mall, comes Hooked, a casual, American-style seafood shack. Fried seafood abounds: shrimp, calamari, oysters. The shrimp po’ boy features crisp, plump morsels overflowing from a crusty baguette. A cluster of snow crab legs, simply steamed and served with drawn butter is worth the (relative) indulgence, pricewise. Pho Long fans should check the back page of the menu: The kitchen demos new dishes for that restaurant here.
