At Bastien's, a retro supper club, it sometimes seems like time has stopped -- back in the days when a steak had to be marbled with fat and no one said a discouraging word about cholesterol. And as if a plain old piece of cheesecake weren't a heart attack waiting to happen, Bastien's wraps the thing in a regular-sized tortilla and then deep-fries it so that the cheese gets all soft and smooshy and the tortilla turns golden brown and crispy. A ball of ice cream -- sometimes it's vanilla, sometimes it's caramel pecan -- comes on the side; the ambulance costs extra.
