Mike’s original 10,000 square feet in an old mill is crammed with hundreds of antique treasures, from mid-century Danish teak sofa tables to luscious Oriental rugs. (Last time we were there, we spied a stunning modern glass top table and four Callagaris chairs for $850 that would look perfect in our kitchen.) The newly opened upstairs showroom is chockfull of less expensive collectibles, kitchenware, posters and tchotchkes. A plus: the savvy social media staff answers shoppers’ questions on Facebook within a few hours.
