A Lithuanian strip mall put together a special space for Valentine's Day 2011: a traditional Lithuanian sitting room made entirely of dark and white chocolate. Almost everything in there is chocolate: the walls,table and chairs, flowers and candles, dishes, utensils and food, even the pet cat!
The roses in particular are exquisitely well done. Only the floor broke the theme: it appears to have been made of plain wood. Oh, well. Check it out http://www.odditycentral.com/news/shopping-mall-creates-perfect-place-for-a-romantic-dinner-a-room-made-of-chocolate.html
Surprisingly, this work of edible art required only about 660 pounds worth of chocolate to create. It measured 17 square meters (roughly 183 square feet), so it wasn't huge -- but it was as big as most dining rooms. It's the work of sculptor Mindaugas Tendziagolskis and his assistants.
On International Women's Day, March 8, the display was broken into pieces and eaten by visitors -- an excellent fate for any piece of chocolate art, wouldn't you say? Source: http://www.extremechocolate.com/weird-and-wonderful-chocolate-art.html
