Hansin Pocha is a Korean style pub with variations of food that you can eat with Korean alcohol such as Soju, Chung ha and etc. I've tried the famous chicken feet menu and yes it's absolutely way too spicy. So what people usually do is pour a bit of bean sprouts soup with the chicken feet so that the spicy sauce gets a little diluted. It's worth trying while you are in Korea if you are good at eating spicy food.
Other than that, Hansin Pocha in Nonhyun is known for being the mecca of "hunting," which is a term for hooking up. You can easily see tables with men and women getting hooked up and drink together later at night.
