Just had lunch at Chil Bo Myun Ok on 6th St. It's a branch of a South Korean restaurant with 4 or 5 locations their. I think they just opened Monday and it was very crowded at lunch time.
Very good naeng myun - better than Yu Chun - I had their house special bibim naeng myun which included some kim chi, other vegegetables, some beef and fish with chili paste. It was very tasty and only oderately spicy.
Also tried their beef soup, it was also very good and fairly hot due to the red pepper. The banchan dishes were all good, nothing exceptional.
The menu had a big section for bbq but it seemed everyone was their for the noodles, at least for lunch.
They're located at:
