Tip #1 for everyone who plans on eating here: Be patient. If you're starving and need food now then maybe this isn't the place for you.
This place is a real ma and pa shop and their staff is very very small. We saw 2 cooks and 2 waitresses. Came here on a Friday night so it was busy. I did notice that there was a couple who yelled at the waitress and left because they had to wait too long for their dishes so I was concerned at first. Once we were seated we received water right away but it did take some time for the waitress to come back to take our order but hey, it was a busy night and they did their best to get to every table. When you're sitting in the restaurant you literally see everything. You see the waitresses running back and forth to get everything done, you see the kitchen and how hard to cooks are working to get everyone's order out. Be patient. They're doing what they can to get to their customers.
Once we ordered it took about 20 minutes to get our food out and it all didn't come out at once, which we didn't mind. The food is absolutely outstanding and everything is made absolutely fresh and hot. I don't want to bash other Korean restaurants (since they're all not bad) but this was by far my favorite and definitely worth the wait. The waitresses didn't necessarily check on us or asked how things were tasting but they made sure our drinks and side dishes were always full.
I know there are a good chunk of negative reviews based on the service but once I was there I understood why service was slow. Its fresh, it's real, and it's pretty darn good.
