Among the prominent personalities included Mukherjee's predecessor Pratibha Patil and former prime minister Manmohan Singh, besides former vice president Hamid Ansari besides a host of opposition leaders.
Among other leaders included CPI-M's Sitaram Yechury, BSP's Satish Chandra Misra, TMC's Dinesh Trivedi and DMK's Kanimozhi.
Breakaway JD(U) leader Sharad Yadav, JD(S) leader Danish Ali, JMM's Hemant Soren, NCP's DP Tripathy, RJD's Manoj Jha, AIUDF leader Badruddin Ajmal, RLD's Mehrajuddin also attended the party.
"Good food, friendly faces and great conversation make for a memorable Iftar! We were honoured to have two former Presidents, Pranab Da and Smt Pratibha Patil ji join us, along with leaders from different political parties, the media, diplomats and many old and new friends," Gandhi said on Twitter after the Iftar.
After much consternation, the party however, later complimented him for his speech for showing the mirror of truth that carried lessons on pluralism and secularism to the Sangh.
Gandhi came along with Mukherjee and while the former president left after sometime, the Congress chief offered to drop him back but Mukherjee politely refused.
Besides pleasantries and photo ops, the short conversation at Gandhi's table revolved around the prime minister's fitness video put out by him on Twitter this morning.
Gandhi described it as "ridiculous" and "bizarre" and asked Yechury to put out his own fitness video in return, as he poked fun at the prime minister.
Earlier, leaders of some opposition parties met at a different location to discuss possibilities of a larger alliance.
Kanimozhi later said, "Everyone wants alliances but today's meeting was a courtesy meeting."
Also present at the Iftar were a large gathering of diplomats, especially from the Islamic countries, including the Ambassador of Russia to India.

These included Ahmed Patel, Ghulam Nabi Azad, Mallikarjun Kharge, Ambika Soni, Janardan Dwivedi, Anand Sharma, Veerappa Moily, Jairam Ramesh, Mukul Wasnik, KV Thomas, Shivraj Chouhan, PJ Kurien and former chief ministers Bhupinder Singh Hooda, Prithviraj Chavan and Shiela Dikshit.
