Must-Visit Places, Must-Eat Food & Budget Stays in Chennai

Hey fellow redditors, I'll be visiting Chennai soon and would love your recommendations on: 1. Must-visit places – I'm open to historical sites, cultural spots, scenic locations, and hidden gems in and around the city. 2. Must-try food – Local delicacies, street food, or iconic restaurants that serve the best South Indian or unique dishes. 3. Budget-friendly stays – Hotels, hostels, or Airbnb options that are affordable yet comfortable and safe. Would appreciate any personal experiences or tips. Thanks in advance!
