You could also show the Bizarre Foods episode where they go to Seoul. The English will probably be over their heads, but the food will be familiar. Also, I like the Eat Your Kimchi video with Korean streetfood. It has subtitles in English or Korean, but I think my students were curious to see the foreign perspective when it comes to Korean food (and it's all positive, so that helps )http://www.eatyourkimchi.com/korean-street-food-wonderfulness
