Travelling Suggestions-- Food

Hello everyone, I’m planning a trip to India and will be visiting Delhi, Bangalore, and Patna. I’ve also heard great things about Kerala and, after some research, found that places like Munnar and Kochi look amazing. Since I’m a huge fan of Indian food, I’d love to explore areas known for their culinary richness. Which destinations would you recommend for the best food experiences? Also, I’ve come across mixed information about Keralan cuisine. I’ve heard that beef is commonly eaten in Kerala—is that true? Could you share some of the most popular dishes from the region? Thanks in advance for your help!
