Want to experience a European café without the jet lag? Head to Burdick. The true test of chocoholism is actually finishing the iced hot chocolate—a deeply decadent concoction poured over ice, and crowned with a veil of whipped cream. If the craving persists, move on to the signature (and adorable) chocolate mice, filled with cinnamon, mocha, or orange. Or snag a spot at one of the café’s tables by the window, and survey the march of humanity in Harvard Square as you linger over any of the 13 truffle varieties and slip into a Proustian peace.
