Finally, I ate the famous Sichuan cuisine chain Gaga duck brain shell in Ya'an. The taste is very Sichuan, even if it is slightly spicy, we can't resist it. It depends on a few bottles of cold beer to insist on the avant-garde decoration outside the store. It is a place suitable for young people to gather. The service staff is satisfactory regardless of their attitude and ability, especially when it is still open at 3 pm, which is really dedicated compared to the surrounding restaurants.
