Bed Bath & Beyond

The short answer is no, not that I have found. Depending upon what you are actually looking for, there are some options but there is not that sort of one-stop shop culture here.

Darn. I was going to suggest Casa. You may want to look at Maison du Monde. It is kind of like Pier One. They have an internet site but they also have a store in Brussels (as well as other locations) that seem to have more of the smaller items. http://www.maisonsdumonde.com

There is also a couple stores in Woluwe Shopping Center that may be worth checking out if you are in the Brussels area - Habitat, Sia or Zara-home.
