Just because Mad Men is ending doesn't mean your Midcentury Modern obsession has to. And a lovely place to explore said obsession is Red Modern. Note: This ain't no thrift shop. That's true when it comes to the furniture emporium's stock and its according (sometimes eye-popping) prices. Walking through the showroom is like walking through a furniture buff's wildest fantasy. Mint green Hans Wegner papa bear chairs? Check. Impeccable rosewood credenza? Um, take your pick. How about a signed lithograph from Frank Gehry? Calm down — yes. Before you head over, make a list of what you really, really want. Because it'll be easier than you imagine to get distracted.
