You don't have to be rich to come here. You can easily enjoy a quiet and tasty soup and sandwich lunch downstairs in the cafe. The stationery shop is also a great place to pick up unique cards, notebooks and paper. The MAC cosmetics boutique is also a great place to have a stylist help you pick out the best colors for your complexion and style.
You *DO*, on the other hand, have to be rich if you want to shop their exclusive designer boutiques like Louis Vuitton, Longchamps Paris, Michael Kors or Aquascutum and absolutely need to have whatever is hottest off the runway. I personally don't and I'm quite content looking on ebay or a handful of other sites for the same items at a fraction of the price.
Another plus: Ogilvy's is the only place in Montreal that sells Annick Goutal perfumes so if you want to smell like a piece of heaven, come here to get it.
