After a successful pop-up shop in Wicker Park last year, custom furniture maker Interior Define has opened a brick-and-mortar store in Lincoln Park at 833 West Armitage Avenue. Stop by tonight for the grand opening, featuring live music, artist installations, a margarita bar, and D.I.Y. party favors—as well as a new custom sofa collection. The party continues this weekend with complimentary refreshments from neighborhood eateries on Saturday and Sunday from 10 a.m. to 7 p.m.

Restoration Hardware (1300 N. Dearborn Pkwy.) is offering up to 30 percent off select lighting from now until October 19. You’ll get deals on chandeliers, table lamps, vintage outdoor lighting, and more. You’ll also gawk at the enormous new space, which includes a swanky new wine bar and café dreamed up by Gilt Bar’s Brendan Sodikoff.

From now until October 17, you can get 20 percent off USM Modular Furniture, a sleek storage and office furniture line from Switzerland, at contemporary furnishings spot Haute Living (222 W. Kinzie Ave.).

Calling all ghosts and goblins: From now until October 31, Williams-Sonoma (900 N. Michigan Ave.) is offering 30 percent off Halloween treats, tools, bakeware, décor—think spooky tablecloths and skull-shaped punchbowls—and more.

Tabula Tua, the high-end tabletop shop in Lincoln Park, has opened a new location at Oakbrook Center Mall (100 Oakbrook Center, Oak Brook).

And the CB2 collabs continue: The store (800 W. North Ave.) has joined forces with the artist Lenny Kravitz on a line of furniture and housewares inspired by Kravitz’s residences in Brazil, Paris, and the Bahamas (and which veer a little ’70s in style). You can shop the collection online or in store now.
