Kartell 4470 - Gastone Trolley
I've been shopping for a bar cart for some time now and gosh is the Gastone trolley by Kartell just absolute perfection. Perfect for serving food and drinks indoors and out. It also comes in several colors (I love the sea blue) so it's sure to fit in with any decor. Even better -- it is completely foldable so that you can put it easily away when not in use.
