The theme, according to Nutter spokeswoman Jennifer Crandall, is the neighborhoods of Philadelphia, and those at the gala will savor a menu that includes cheesesteaks and samplings from restaurants around the city. The celebration has been dubbed "Philadelphia Realized."
The entertainment? Local bands, dance troupes and other acts, Crandall said.
The 8 p.m. event will cap a day of inaugural activities.
The formal swearing-in of the new mayor is scheduled for 10 a.m. at the Academy of Music. Nutter will deliver his inaugural address after taking the oath of office. His senior deputies will be sworn in at City Hall about 12:30 p.m.
A mentorship luncheon for Philadelphia students and mentors from the business community will follow at the Park Hyatt at the Bellevue hotel.
On Tuesday from 4 to 8 p.m., the public is being invited to stop by City Hall for an open house at the courtyard, Conversation Hall, and the Mayor's Reception Room.
Any profit from the gala will support local arts and education nonprofits, officials said.
