Atlantic Fish Company on Boylston Street has earned first place at the city's annual Chowderfest. The atmosphere is casual and the bar is lively. Once little more than a hole-in-the wall, it is now an upscale space with warm wood trim and intimate booths. Choose from a variety of seafood entrees that are fresh and well prepared. Fried clams, an overflowing lobster roll and blackened salmon are favorites; steak and chicken are available, but vegetarians face slim pickings.
