Those who don't believe it's possible to step back in time have not set foot in architect Jonathan Sandvick's radiant masterpiece. It's like walking into a colorized movie -- one set more than a century ago. Five stories of 1890-style decor glisten under a glass skylight. On every floor, in every corner, surprises reward the observant eye. Fierce-looking gargoyles encircle the 300-foot glass roof. Lions' heads top sleek black columns. And the railings teem with gilded swirls. After its two-year, $60 million renovation, the historic Arcade has reopened as a 293-room Hyatt Regency hotel, but shops and restaurants will occupy the lower two floors, preserving public access to this architectural beauty.
