I love clam chowder, and I frequently visit Boston Chowda Co., as their sign says in the Prudential Center. I don't think I've ever tried anything BUT the clam chowder, but there's never been any reason to. If you can't stand the wait at Legal's, head over to the food court and pick up some chowda. The best thing is that you can finish your meal with a variety of fare from the other food court places.
Pros: Clam Chowder, Cheap Drinks
