Chief Minister Arvind Kejriwal, his deputy Manish Sisodia, Environment Minister Imran Hussain, and Tourism Minister Kapil Mishra were among the dignitaries who attended the function.
This is the first function attended by Kejriwal at Raj Niwas after Baijal took over as Lt Governor.
Baijal's predecessor Najeeb Jung had been at loggerheads with the AAP dispensation on a range of issues including transfers and postings of bureaucrats.
Senior officers working in LG secretariat and Delhi government were also present.
