Chongqing claims to be the home of hot pot (huoguo). The fun of hot pot is you can select from a number of different soup bases from spicy to almost a chicken noodle broth. Then you choose a number of dipping sauces and finally the meats and vegetables to throw into the pot that you cook at your own pace, similar in a way to fondue. Hot pot originated as the food of poor boatman who needed the warmth of the broth and the substance of tripe. So if you fancy trying the authentic stuff with chillies hotter than anywhere else in China, you are in for a real treat with the city's offerings. As the tears stream from your eyes and your lips swell with numbing pain, you will know you are eating authentic hot pot.
If you really can't handle the spice, "wo bu yao la" means "I don't want it spicy." The Little Swan the city's best hot pot, but it can be a bit expensive. Yangrou Guan on Minzu Lu and Minsheng Lu are both good streets for hot pot and also heaps of street food and hole-in-the-wall restaurants.
