Kayagum is amazing! I honestly don't know how I've been living without coming here! When I wake up at 3 in the morning craving Korean food, my boyfriend and I will just drive here (it's a 15 minute drive from our place). The servers are always very friendly. The ambiance is also amazing (I have sensitive ears so a place that's not too loud is a huge bonus for me). The food is also very delicious but personally I wouldn't get the sushi very late at night. Best place ever!
