There is no best food, only your favorite food. I would like to recommend a good hotpot restaurant, Zhuben Tomato Hotpot. It is reported that this restaurant has two stores in Taiyuan, namely Kangning Jiayuan and Changfeng Street. I forgot the detailed address, too. You can search Meituan. This store has a voucher in Meituan, which contains the detailed address and ordering phone number.
Why do you recommend this store? First of all, their tomato soup is really delicious. Unlike other hot pot restaurants, their tomato soup is particularly rich. Their tomato pot is just sweet and sour, and it is full of sweetness.
for dishes, I recommend spicy beef, hairy belly, and fat beef, which I must order every time I go. It's delicious and highly recommended.
