Was just there with about 15 buds from my Korean language Meetup. The restaurant is clean and spacious and I swear they have the quietest hood vents in the city.
All you can eat 24-hours a day...yes please! We had a great time and they were super helpful and accommodating. Food was terrific and the service was speedy. Just a tip to those not used to Korean places, there is a small doorbell button on your table. Use this whenever you need anything from the staff. If you buzz it they will come running. Sometimes I see people trying hard to flag someone down from across the restaurant. Use the doorbell. It's much more convenient!!
Word of warning: when they say the spicy chicken is spicy...they really mean it! Oh so good and worth the pain! The side dishes were great and plentiful too. Just ask if you want more of anything.
