Our opinion: Eh. We love the idea of a mirror in a kitchen, but we'd steer more towards a big, antique one to hang on the wall. We imagine these being hard to keep clean, too.
However, we could see this idea working in a limited capacity- say, in a small section of cabinets over a bar area. And we like the antiqued mirrors on the right. They're a little more subdued, less funhouse-at-the-fair.
This could be a really easy upgrade for a small rental kitchen. You can buy mirror tiles or have them cut pretty easily to fit the front of your cabinets. Then you can cook and have a conversation with the people standing behind you without having to turn around! Fun!
Anyone have mirrored cabinets in their kitchen? What's your verdict?
