Here's a look at the best new New York restaurants, hotels, party rooms, corporate event venues, conference centers, and private rooms to open this fall. These new and renovated New York venues can accommodate groups large or small for private and corporate events, meetings, business dinners, cocktail parties, conferences, weddings, and more.

A dedicated space for private dining, Sopra opened in May from the team behind Amali restaurant. Located above Amali with a private entrance, the venue philosophy is informed by the Mediterranean dining tradition of communal dining and socializing. The design from Mapos includes marble-topped bars, custom furniture made from reclaimed wood, and photographs of the staff's families. The venue consists of two rooms separated by a sliding barn door. The chef's kitchen and loft space features an open kitchen where the chef prepares a seated dinner for 20 guests at one communal table or 30 at separate tables. The loft holds 50 for receptions. The Fireplace Room seats 30 or holds 35 for receptions. Used together, the two spaces hold 60 for dinner or 90 for receptions. The menu changes seasonally and is sourced from local green markets and nearby farms.

Park Hyatt New York, the flagship property of the Hyatt Hotels luxury brand, opened in August. The Midtown Manhattan property occupies the first 25 floors of the 90-story One57 skyscraper and has 210 rooms, nearly half of them suites. Food and beverage options include the 70-seat Living Room lounge and the 96-seat Back Room at One57. The bar, overlooking Carnegie Hall, seats 37. The hotel's 8,000 square feet of meeting space includes three residential-style breakout rooms, a boardroom with an attached terrace, and a centerpiece ballroom called the Onyx Room. The ballroom is wrapped in illuminated white onyx and seats 200 for dinner or holds 450 for receptions. The property also includes a 25th-floor spa with six treatment rooms and its own terrace, as well as an indoor pool.

Space Ibiza New York, an offshoot of the long-running Spanish nightclub, opened in Hell's Kitchen this month. Designed by ICrave, the 20,000-square-foot club has several rooms, each with a different look. The multilevel main room with floor-to-ceiling windows has dance platforms and a DJ booth; the container lounge has its own DJ booth built from shipyard containers; and the rooftop terrace offers skyline views. Anthem Sound, Stage & Lighting set up the systems, which include features such as a Funktion One sound system, an oversize disco ball, four custom intelligent lighting UFO spheres, and cryogenics. The entire venue holds 1,300 people for receptions.

Haus, a TriBeCa nightclub, took over the former Canal Room spot in June. The 5,300-square-foot space from Rawlins Design has a gilded DJ booth, a dance floor, tiered V.I.P. seating, a massive overhead chandelier, and a 34-foot-long bar inlaid with semiprecious stones. It holds 400 guests for receptions.

The Venue at 409, a meatpacking district event space from EMM Group, opened in June. The 6,000-square-foot space holds 550 people for receptions and has private dining available on a mezzanine level. The space has exposed brick walls, wood flooring, and a seasonal patio; catering is available from chef Hung Huynh and Catch restaurant.

Below the Venue at 409 is the Brickwood, also from EMM Group along with nightlife veteran Ellington Keys. The decadent nightlife concept, designed by New World Design Builders and opened in June, consists of a lounge decked in jewel tones, rich velvet textiles, and exposed brick designed to evoke a flapper-style lounge, as well as a modern club room with a DJ booth. Each space holds 150 for receptions or 300 when combined. The venue has two 52-inch plasma screens and other audiovisual equipment.

Blenheim, a new farm-to-table American restaurant, debuted in May in the West Village. Produce and livestock from restauranteurs Morten Sohlberg and Min Ye of Smörgås Chef Restaurant Group's 150-acre farm in the Catskill Mountains make up the menu and are served with biodynamic wineries and cocktails made with ingredients from the farm. The 45-seat eatery has a private event room, the Tool Shed, that offers a semi-enclosed space with seating for 10. A seasonal patio seats 26.

A team from the former downtown fixture Chanterelle—chef David Waltuck and general manager George Stinson—have opened their own place, Élan. The contemporary restaurant, located in Gramercy, seats 48 at banquettes and tables in the dining room and 12 in a front bar area, which also includes drink rails. An art wall near the bar will serve as rotating canvas, with work from a new artist every six months. It debuted with a tapestry by Chuck Close.

The 45-seat East Village restaurant Tuome opened in August from Eleven Madison Park alum Thomas Chen. The menu mixes contemporary American and Asian flavors in dishes such as octopus with house-made XO sauce. The rustic decor makes use of reclaimed materials such as a wall of circa-1920 wool spools from a Pennsylvania knitting factor, a bar with stools from a college science lab, and 1890s light fixtures from a Philadelphia milk factory.

The Kimberley Hotel has a new lobby-level restaurant, Bistango. The Midtown East restaurant is the latest location for the Italian eatery, which originally opened in Kips Bay. Guests enter the new spot, which opened in August, through a corridor lined with wood and glass cases displaying the wine collection, and the dining room has an open kitchen. The restaurant seats 40 and includes a private dining room for six.
