Attention gourmets! The Eliseyev Emporium, the most famous food shop in St. Petersburg, is housed in a beautiful building designed in the early 20C by Gavriil Baranovsky. Even if you don't feel like indulging, step inside just to admire the lavish Art Nouveau décor (mosaics, wrought iron, gilding, crystal chandeliers and mirrors) illuminated by large stained glass windows.
