The Cadbury store is in the downtown pedestrian area - not sure of the address but it should be easy to find. The restaurant (Blinis) is just across the river from there at the end of the bridge. One word of caution on the chocolate picture. Make sure to hold it flat for 5-10 minutes to ensure the food colouring doesn't run. It should be fine, but don't take chances. And we found that nobody actually ate the chocolate picture - everyone thought it was too 'beautiful'. And have the photo ready beforehand.

Enjoy, Alan
