This year saw the opening of many significant event and meeting venues in Los Angeles. Here's a look at the best restaurants, party rooms, hotels, corporate event venues, conference centers, and private rooms to open in 2015. These new and renovated Los Angeles venues suit groups large or small for private and corporate events, business dinners, cocktail parties, conferences, weddings, and more.

Debuted in October, the new Broad museum of contemporary art on Grand Avenue was the most significant cultural opening of the year in Los Angeles, contributing to the city’s growing reputation as a cultural center. The new Diller Scofidio & Renfro 120,000-square-foot design includes a third-floor gallery with nearly an acre of column-free space that displays artwork from the vast Broad family collections. On the first floor, the lobby includes a gallery for special exhibitions, bringing the venue’s total gallery space to more than 50,000 square feet.

Two decades after the Petersen Automotive Museum opened, it closed for a total overhaul in its 21st year. It reopened in December with a complete redesign, including 25 new galleries totaling more than 100,000 square feet. The new exhibits now contain Disney Pixar Cars characters, Xbox/Forza simulators, BMW art cars, the new $400,000 Ford GT, a motorsports gallery, virtual tours for iPhone and iPad, and more. There is a variety of private event space on the Petersen’s four floors, from intimate classrooms and the Founders Lounge to the Grand Salon, which holds 650 guests for receptions or seats 400 in more than 13,000 square feet, and the 8,000-square-foot Pavilion Rooftop and Terrace, which holds 300 for receptions or seats 200.
