We boarded the Trans-Siberian Railway in Moscow on a foggy, freezing February night. When we disembarked in Beijing, it was a bright March afternoon, and we had traveled more than 4,800 miles. The Trans-Siberian dining cars are independently owned and operated, serving the food of whatever country the train is in. Crispy chicken in the Chinese dining car, kolbasa in the Russian dining car, and more. It was an exciting (and diversely delicious) ride; here's what we ate along the way.
