You go to a large supermarket, and there are packaged Peony Swallows, Luoyang Swallows, similar to Peony cake; These big discounts are available in Carrefour, Dennis and Wangfujing.
If you don't go too far, I suggest you go to Zhu Min Street, where there are famous elm garden roast chicken and Dongjiadaokou roast chicken rabbit meat. There is also the rabbit manager of Xiaobeimen, with special chicken, dried rabbit meat and roasted rabbit pieces. The address is on the northwest side of the intersection of Huancheng North Road and Xinjie (formerly Old Town Stadium), and it is not far from you by taxi.
