We're giving America's favorite condiment a swirl in this deliciously drippy episode. Seafood dishes like hot lobster rolls and blue crab spaghetti get dressed in robes of butter at restaurants in Boston and New York while bakeries in San Francisco, Washington, DC and Atlanta bring butter to new heights in their flaky pastries. We've also got butter in places you never even thought of -- on top of knish sandwiches and melted into mochi.
