Wanted to note a great lunch a couple of weeks ago at a new place called Gung Ho, at 680 8th Street (furniture district/potrero hill). Apparently this is the permanent location of Seoul Patch, which was a pop up.
We both had korean fried chicken sandwiches ($11), which came with a generous portion of double fried boneless thigh meat that was juicy, crispy, and seemingly fresh from the fryer. It was served on a soft bun with a daikon slaw and a spicy sauce that seemed to be gochujang. This was better than I expected--a nice twist on a fried chicken sandwich, a little bit sweet, a little bit spicey, and a little bit tangy. This was good, though it didn't reach the heights of sandwich heaven.
We also ordered sides of brussels sprouts and nori fries ($4 each). The fries were tasty and maybe even fresh cut (can't remember now), and were served with a homemade "Korean ketchup" which was (I think) the same as the gochujang that was on the kfc sandwich. They were tasty but a little too salty. The brussels on the other hand were fantastic, and would be my primary reason to return. Well caramelized, salty but in a good way, and tender. The order was a large portion, yet we ate every one.
I would return for more brussels as well as to try their ramen and bibimbap, both of which looked very good as they passed by us on their way to other tables. They have a different menu for lunch and dinner, including a different prep of the Brussels sprouts than what we had at lunch.
