About Chennai
City overview
Chennai is the Bay of Bengal capital where colonial Fort St George, Mylapore temple streets, Carnatic music halls, and IT corridors stretch along a hot, humid coast. The visitor map centers on George Town, Mylapore, Egmore, T Nagar, Besant Nagar, and the ECR/OMR edge south of the Adyar River.
Food & drink
Chennai food is built on idli, dosa, sambar, pongal, vada, filter coffee, Chettinad chicken, biryani, sundal, and seafood from the coast. Mylapore, T Nagar, Sowcarpet, Marina Beach stalls, and Buhari-style biryani houses are practical food anchors. Prices stay moderate outside luxury hotels, and December music-season canteen meals are a real cultural draw.
