Hidden among the oak-paneled law firms in the historic 1926 PacMutual Plaza tower, Please Do Not Enter shuns the drywall and dropped ceilings of its neighbors in exchange for an open, minimalist space. All polished concrete and exposed brick, the hybrid luxury boutique/gallery houses a meticulously curated collection of men's fashion, art, furniture and accessories. Open by appointment since April, it's owned by Nicolas Libert and Emmanuel Renoird, who choose items that are unique or produced in very small editions, sometimes collaborating directly with artists and designers. French expats who are romantic and business partners, Libert and Renoird have a background in interior design and high-end real estate. The two are voracious art and design collectors who bring their keen eye to a constantly rotating selection of high-quality goods. Pieces range from $15 “archispecs” — a playful paper take on Le Corbusier's famous eyeglasses — to a $200,000 metal sculpture by Arik Levy. “We choose pieces that are a combination of novel materials and high craftsmanship,” Libert says. —Marissa Gluck
