Seminars and company events
The Cosmopolitan Hotel and Restaurant takes group events for 30 to 300 guests, from meetings and team dinners to large receptions, with ten period guest rooms on the upper floor. It occupies the Casa de Bandini at 2660 Calhoun Street, inside Old Town San Diego State Historic Park.
For company groups, the draw is the setting combined with full service. Events use the garden courtyards and the indoor rooms of the restored building, and the in-house team runs the banquet and the bar. The restaurant serves lunch and dinner, so a meeting can move straight into a meal without a transfer. The state park around the hotel, with museums, shops and restored buildings from the 19th century, gives participants something to explore before or after the program, and it suits a guided walk as part of a team outing.
Weddings and receptions
Weddings are the core of the event offer. The Cosmopolitan hosts intimate ceremonies, rehearsal dinners, bridal showers and receptions for up to 300 guests. Ceremonies can take place at the hotel or at another historic or scenic spot in Old Town, and a Cosmopolitan planner helps with the permits, fees and bookings an off-site ceremony requires. Packages can be adjusted to the couple, and linens and table settings are included in the service. Wedding parties sometimes reserve the whole upstairs floor of guest rooms for the weekend.
Rooms and capacities
The venue states a range of 30 to 300 guests, using the garden courtyards and the indoor spaces of the hotel and restaurant. Named rooms and figures for each space are not published and are given by the events team on request.
Accommodation
Upstairs, the hotel has ten guest rooms furnished in period style. They can be reserved for a wedding party or for the hosts and speakers of a group event.
Catering
All food and drink are handled in-house, with full-service banquet menus and bar packages. The restaurant also runs seasonal menus, such as a Thanksgiving buffet, which shows the kitchen's capacity for large seatings.
History and setting
Juan Bandini had the adobe built between 1827 and 1829 as his home and a social center of the town. It holds an estimated 10,000 adobe bricks, each weighing up to 60 pounds, and is said to have had the first wooden floor in San Diego, where the waltz was first danced in California. The Seeley family later bought the house, added a second story and opened it in 1869 as a hotel, restaurant and stagecoach office. It went on to serve as an olive cannery and a Mexican restaurant before being restored to its 1870s appearance. It is a contributing property in a district listed on the National Register of Historic Places.
Getting there
The Old Town Transit Center, served by the San Diego Trolley and the Coaster commuter train, is a short walk away. San Diego International Airport is about 10 minutes by car.
