I don't know much about the food, but I can talk about the places to play. The parking fees for the Terracotta Warriors and Horses in the morning and Huaqing Palace in the afternoon are 2 yuan/car. If there is no limit on the day, if you drive by car, it is recommended to eat in the urban area. You know, if you take the bus, take bus No.36/914/915 at the East Square of Xi 'an Railway Station. Go to the Terracotta Warriors and Horses first, try to get up early and there are few people. 12 yuan is everywhere, but Huaqing Palace is different. Online tickets are cheap. The Terracotta Warriors and Horses focus on the No.1 pit and the cultural relics exhibition hall. There are often other museums fighting each other, which is worth recommending. There is a guide map at the entrance of Huaqing Palace, or you can take a cableway. It is faster to go up and down Mount Li.
