Instead of the cooking class we were offered foodie tour due to late confirmation from our side. The guide Key was very knowledgable and friendly presenting not only food, but also the history of Chengdu and China, so we liked the tour a lot. The places we visited were quite hardcore for European tourist (difficult to find and very authentic both in terms of food and cleanliness), but in case you want to get closer to locals, this is a must!..
