The Umbra store is a great place to get some sweet wares for your house - especially if you're sick of buying the same coffee table from IKEA that all of your friends have.
I bought my friend a really nice dark wood jewellery box from Umbra this weekend for $35 which I thought was a pretty fair price for such a unique piece. However, I have to say I didn't find everything in there overly affordable. Some of the stuff even seemed pretty over-priced ($45 salad tongs!)
But for a boutique-y store in Queen West it's not surprising that they're over charging a bit. And their stuff is definitely unique. As Vanessa V said, it's full of bright colours, plastic and that kind of clean and minimalistic conceptual store layout that makes you want to buy one of everything so your house will look just the same. If you have some cash to burn, this is a great place to do it, but if you want some more affordable pieces, you might want to visit the Swedish mega-store.
