Visiting Chennai with a group of 20 – Need Suggestions!

Hey everyone, We are a group of 20 people traveling from Gujarat to Chennai soon, and we’d love some suggestions! This is our first time visiting, and we want to make the most of our trip. * What are the must-visit places in and around Chennai? * Any recommendations for good local food spots (especially South Indian dishes)? * What’s the best way to get around the city for a large group? * Any cultural or unique experiences we shouldn't miss? * Any tips for budgeting/staying safe while exploring the city? Would really appreciate any insights from locals or experienced travelers. Thanks in advance!
