Epernay is a very small city, with vineyards within the city limits. This allows you to literally hike through the vineyards, and offers some spectacular views. Stop by the tourist office in downtown Epernay (in the Hotel de Ville), and pick up a map of the city. Ask about the foot path through the vineyards. It is a 10 minute walk from there before you are in the vineyards, which extend for miles. You can do a short, 1 hour hike or just keep going. I walked for about 2.5 hours in one direction, and descended upon a little village. This is surely a great way to entertain yourself in this beautiful region, and the price is right!
At Moet & Chandon you can find this Chandelier made of Champagne flutes. It's not really a lamp, however. Just glasses - just for the fun of it.
