[12] An alternate version of the song was also produced, sung by British Sri Lankan musicians Charles Bosco and Arjun.

[15] "Chennai City Gangsta", described by Anirudh as a "rave party track",[16] includes vocals by Adhi of Hiphop Tamizha, and Punjabi rapper Hard Kaur.

Adhi had earlier collaborated with Anirudh for the title track of Ethir Neechal (2013), and described "Chennai City Gangsta" as a thematic follow-up to that song.

[22][23] Vipin of Music Aloud summarised "It is indeed a hat-trick of winners in Tamil for Anirudh Ravichander , with Vanakkam Chennai.

[24] Karthik of Milliblog wrote "Vanakkam Chennai is an interesting soundtrack, but has Anirudh's past catching up too early in his career".

[28] Ahead of release, the film was denied entertainment tax exemption, despite meeting the eligibility criteria.

[32] S Saraswathi of Rediff.com said, "Vanakkam Chennai is a fun-filled, but slow paced romantic film that does not boast of a great or original storyline.

"[33] Prashanth Reddy of Desimartini said, "Anirudh's music is a huge positive and I can't seem to get a few of the background tunes out of my head.

"[34] Writing for The Hindu, Baradwaj Rangan said, "Seeing Vanakkam Chennai is to be reminded of how stupidly happy a light-hearted love story can make us feel.

[35] Sify said, "The film has nothing new to offer but is still enjoyable due to its glossy packaging, rich visuals and lots of fun".

[36] Malini Mannath of The New Indian Express wrote, "Sweet and warm at places, the film is a monotonous journey on the whole.
