If you visit Paris a visit to Galeries Lafayette is a must - even if you don't buy anything go to see the magnificent central cupola which has a beautiful glass and steel dome, and Art Nouveau staircase built in 1912 by the architect Cahnautin. The store - all 10 stories of it - is classified as an historic monument. Don't forget to pick up your map at the information counter, you'll need it to find where anything is - don't think of browsing, not unless you have a fortnight to spare, it's HUGE! Looks more like a theatre or an opera house.
