First of all, Cai Jiu Skewers, a famous restaurant with a history, is worth a try. It has been known far and wide since the 1990s. Its signature is the fat and thin beef skewers and duck blood, typical of Sichuan and Chongqing's red oil skewers. In addition, regular halal offerings have made it a popular choice for many Muslims.
Secondly, Vegetarian Love Skewer is also a skewer restaurant with a good reputation in Leshan. This restaurant also has a wide selection of vegetarian dishes. Gluten, bean curd, fungus, green bamboo shoots, potato slices and so on, there are all kinds of things, and every one of them is delicious. If you don't eat meat, consider this store.
Finally, Xiao Dian Zhang San Skewers is different from the first two stores. It is a small restaurant, no queue is required and the price is more affordable than the other stores. In particular, the skewer pot base and sauce are homemade and have a very authentic flavor. Pair it with a beer from Gurley's and a skewer meal becomes a relaxing and nice night of drinking.
Overall, the aroma of skewers wafts all over the city of Leshan, so I'm sure there's one that suits your taste. These three restaurants are just one of the good choices. Perhaps you'd prefer to discover more, or your own taste preferences are different, so try again and again, you'll always find something new.
