How can chowdah get bettah? Dogfish Head believes beer is the key. Their new Hard Tack Clam Chowder ($4) is based on a recipe from “Moby Dick,” and even bettah, it’s infused with Dogfish’s 60 Minute IPA. Wash it down with — what else? — more beer in the form of some Indian Brown Ale and we figure you’ll be having a whale of a time.
