In the corner of what seems like another cubicle-packed, corporate office (it's actually the City Club) lies the serene, pristine and see-and-be-seen Cafe Voil�. Also a gourmet catering operation, this cafe serves up Illy espresso, 20 rare teas, soups, a small assortment of delectable salads, including a striking beet salad ($4.50) as well as a dense lentil salad ($4.50), and gigantic gourmet sandwiches, packed full of goodness, that go for a mere $5.50.
