The get-together was organized to have a close contact among MLAs.
According to news agency PTI, the MLAs are also believed to have pledged their support to Kejriwal, especially after sacked minister Kapil Mishra alleged that Health Minister Satyendar Jain gave Rs 2 crore to the chief minister.
Kasturba Nagar MLA Mandanlal said the programme went off well as the chief minister interacted with his party legislators and their families.
Kumar Vishwas, Sanjay Singh and Raghav Chadha skipped the event
"The dinner was for AAP MLAs and their families. Everyone missed KV (Kumar Vishwas), SS (Sanjay Singh), RC (Raghav Chadha), DP (Dilip Pandey)," MLA Alka Lamba tweeted.
Reports say MLAs Bhavana Gaur and Saurabh Bharadwaj were not present as they were out of town. Burari MLA Sanjeev Jha is on an indefinite fast at Jantar Mantar to protest against suspended MLA Mishra's corruption allegations.
