Cult seafood favorite and hole-in-the-wall
No-Name Restaurant (15 Fish Pier, Northern Ave., 617/338-7539, noon–7 p.m. Mon.–Sat.; closed Sun., $5–23) is acclaimed for its seafood literally right off the boat. The menu changes depending on what’s in season, but always includes some variation on a tummy-warming fisherman’s stew. Other entrées are simply fried or baked, offering unadulterated seafood at half the price of more celebrated restaurants.
