With its light-wood interior, Italian coffee drinks, and Austrian desserts, Café Demetrio looks as if it's been imported from the Alps. All that's missing is some snow and a Saint Bernard or two. But the coziness of this coffee shop doesn't mean we should only enjoy it during the cooler weather. The gourmet frozen cappuccino, the coffee mousse, and the Kahlúa ice cream make the transition from mild winter to hot summer easy as pie or, in Alpine land, easy as tarts.
