Here's a look at the best new and renovated venues in San Diego such as corporate event venues, party rooms, conference centers, restaurants with private rooms, unique venues, and more. These event and meeting spaces can accommodate groups large or small for fall entertaining including business dinners, cocktail parties, conferences, and private and corporate events.

Avant, the new restaurant at Rancho Bernardo Inn, has three spaces for private events: La Taberna seats 50 and overlooks the golf course; El Biz seats 18 in a boardroom style in front of a fireplace; and Avant Kitchen seats 12 at an open-concept performance kitchen. The warm decor has whimsical touches in its 139-seat dining room, including house-made mustard on tap.

Andaz San Diego has added a retractable roof to create an indoor-outdoor venue called RoofTop600 as part of a renovation to the hotel's lobby and event spaces. The rooftop venue also features new cabana beds and outdoor seating. Future phases of the renovation will include new decor and furnishings in the main lobby and the Andaz Wine Bar, as well as the transformation of the existing nightclub into a private venue for meetings and events.

Located in the Gaslamp Quarter, Bailiwick, a playful restaurant and cocktail spot, has decor that mixes chandeliers, birdcages, and claw-foot bathtubs. Staff will offer guests Lewis bags and wooden mallets to guests to crush their own ice. The 3,000-square-foot space seats about 50 guests and fits 215 for receptions. Buyouts are available.

Connected to the Viejas Casino, the 128-room Viejas Hotel offers several spaces for meetings and events, including receptions planned around the pool. The casino also offers the 500-person Dreamcatcher Lounge, and a private dining room at the Grove Steakhouse, which opens this fall.

Located in a historic brick building, the unpretentious Southpaw Social Club is an American restaurant and bar that opened in late June near Petco Park. Its three patios all have a different feel—one with a fire pit and and lawn chairs covered in bright fabrics, another with picnic tables, and a third with bistro tables and chairs. The 5,000-square-foot restaurant seats 150 or holds 250 for receptions.

Tracy Borkum's second Cucina Enoteca is opening this month at Del Mar's Flower Hill Promenade. The two-story, 7,000-square-foot restaurant has a modern-kitchen-meets-historic-farmhouse concept, and the menu will feature Italian dishes with a California flare including pasta, artisanal breads, and house-made sausage. The design concept is similar to the Cucina Enoteca in Irvine (pictured).

Sycamore Den is a new cocktail lounge in Normal Heights that pays tribute to the late-'70s middle-class family—think wood paneling, a player piano, and colorful vintage light fixtures. Its beverage menu is heavy on classic cocktails and features 24 beers on tap. The 1,500-square-foot space accommodates 95 for receptions and seats 56.
