Prominent leaders like Shiv Sena chief Bal Thackeray, his son Udhav and their families cast their votes around noon.
The Sena, weakened after Raj Thackeray broke away floated his own party, is optimistic that it will win the prestigious and the most cash rich corporation in the country.
Raj Thackeray, whose party many consider to be the dark horse, also voted during the day.
