Also, they're mostly talking about food and it's not really hard to understand. It's the kind of show where the guest (Bai Yu) takes the host (Chef Nic) on a tour of their hometown (Xi'an!) and they ... eat a lot? :D
I had fun watching it raw, anyway. But if you happen to find a subbed version, let me know and I'll add a link to it here!
