So, what is gopchang? Well, it's intestines of course. They can come from sheep, cow or pork. I'm not sure which one we ate, but I imagine the taste might be quite similar.
How was it? Well, the flavor was great! I think the thing that would turn off most people who aren't accustomed to eating it would be the texture, which is quite a bit chewy at times. Also, some restaurants can have a very strong smell as well, which I sometimes smell around my neighborhood since there are so many gopchang restaurants.
Our gopchang, ready to eat. You can see some ddeok and veggies fried in. It was slightly spicy, but not very much.
Anyway, I highly recommend trying some gopchang at your local restaurant, or making your way to Hwanghak-dong near Sindang Station where you can choose from many storefronts and street tents that make the stuff.
