I live not too far away and years I finally had a chance to come. I left feeling it was just "ok".
We had the chicken with cheese. I added extra udon. Taste wise I think the chili sauce they use is spot on! It has the right texture and ratio spicy/sweetness/saltiness for me. Totally hit the spot. The side dishes were of good quality. My only complaint is the portion and price. I feel the price is a bit on the high side. I know it's 2018 but I think you can get similar thing at Joons for a bit cheaper. The portion of cheese and udon were quite small in my opinion, especially the udon which was $5.
I wouldn't mind coming back. There are places with better value but the quality of the food makes this a "maybe". But in my area there are just too many choices for Korean food.
